Proper Application of Construction Zone Signage in Manitoba
Amendment to the Manitoba Infrastructure and Transportation Work Zone Traffic Control Manual respecting the establishment of Designated Construction Zones in Manitoba
BACKGROUND
In December, 2013, the Government of Manitoba passed Highway Traffic Act (HTA) amendments that double the set fines for speeding in a designated construction zone (DCZ). The amendments authorize double fines for speeding:
Whether or not there are workers/equipment present; and
Whether or not there is a reduction in the maximum speed within the DCZ
The amendments require traffic authorities, and contractors working on their behalf, to establish DCZs, and to identify them using the signage prescribed in the Designated Construction Zones Regulation.
In addition, the "60 When Passing Workers" sign or any similar sign that links a speed reduction to the presence or absence of workers/equipment is now prohibited from use on all highways throughout Manitoba.
As a result of the introduction of these regulations, several Work Zone Policies, TMPís and STMPís contained in Manitoba Infrastructure and Transportationís Work Zone Traffic Control Manual will need to be revised to comply with the HTA amendments. Until such time as these revisions can be completed and a new edition of the WZTCM issued, this amendment shall provide direction with respect to the establishment of work zones on projects under MIT jurisdiction.
DESIGNATED CONSTRUCTION ZONES
A traffic authority/contractor must establish a work site as a DCZ if the work being undertaken on a road meets ALL of the following conditions:
1. Work is on the roadway portion of a highway, i.e. the area of a highway where vehicles travel, this does not include the shoulder, sidewalk or ditch/median;
2. Work is 4 hours or more in duration;
3. Work is on a paved roadway; and
4. Work is on a road where the maximum speed is 80 km/h or more.
If one or more of the above conditions does not apply to the work being undertaken, then the traffic authority is not required to establish a DCZ. For example, a traffic authority would not be required to establish a DCZ if the work is taking place on a gravel road; or on a road where the regular maximum speed is 50 km/h; or when the work is on the shoulder/sidewalk.
Optional DCZs
A traffic authority has the option of establishing a work site as a DCZ if doing so will enhance the safety of workers and other road users. To do this, the work being undertaken must be road construction, reconstruction, widening, improvement, repair, or other similar work in relation to the road.
DCZ Signage
A traffic authority/contractor is responsible to erect/place the approved signage shown below:
Designated Construction Zone Sign
The beginning of a DCZ must be identified with the "Designated Construction Zone" sign. Drivers must have an unimpeded view of the sign. This sign will replace the Construction Area sign (MC-1) or the "Men and Equipment Working" sign (TC-2) in the TMPís and STMPís contained in this Manual.
In accordance with MITís Standard Construction Specifications, Construction Area Signs are also to be installed at the intersection of every Provincial Trunk Highway or Provincial Road that enters onto the project.
Construction Ends Sign
The end of a DCZ must be marked with the Construction End sign (TC-4 or TC4 DB). Drivers must have an unimpeded view of the sign.
Speed Fines Double Warning Sign
At least one Speed Fines Double sign (MR-179) must be placed within a DCZ and be no more than 150 m after the "Designated Construction Zone" sign which marks the beginning of the DCZ.
A traffic authority/contractor may place more than one Speed Fines Double sign in a DCZ to heighten driver awareness. The sign may also be used to mark a portion of road within the DCZ that intersects with another roadway. For example, where a high volume road intersects with a DCZ, the traffic authority/contractor may use the "Speed Fines Double" sign to warn drivers entering the DCZ.
Bilingual Traffic Signing
Bilingual Traffic Signing Areas as identified in Policy 900-A-7 of this Manual shall be signed in both official languages using either the bilingual sign, or separate English and French signs with the French sign installed the English sign, at a distance of approximately 30m.
SPEED REDUCTIONS
Only traffic authorities are authorised to approve speed reductions in work zones. A traffic authority may reduce the maximum speed in all or part(s) of a work zone.
Longer work zones may have a number of reduced speed areas to enhance the safety of workers and road users.
In the past, traffic authorities/contractors commonly used the "60 When Passing Workers" sign to inform drivers to reduce their speed. This sign, and any similar sign
that links a speed reduction to the presence or absence of workers/equipment, is now prohibited from use on all highways throughout Manitoba.
As a result Policy 900-C-7 in this Manual is no longer valid.
Furthermore, any TMP or STMP in this Manual using the ì"60 when Passing Workers" sign shall be modified to eliminate the use of this sign.
Speed Reduction Signage
Traffic authorities/contractors must now identify all maximum speed reductions in work zones using the sequence of regulatory signage detailed below:
Reduced-Speed Ahead Warning Sign
A reduced-speed ahead warning sign (WB-9) is to be placed in advance of the speed reduction.
"Maximum Speed Signs
The beginning of a reduced-speed area must be identified using a regulatory
"Maximum Speed" sign (RB-1).
The end of a reduced-speed area MUST be identified using a regulatory "Maximum Speed" sign (RB-1) to inform drivers that they may increase their speed to the normal posted maximum.
All existing regulatory speed signs within the reduced speed zone must be covered.
Approved Speed Reductions
As outlined in Policy 900-C-6 of this Manual, The Director of Traffic Engineering has the delegated authority to set speed limits within construction and maintenance areas on provincial highways.
The following common work zone conditions and hazards have been granted blanket pre-approval for regulatory speed reductions. All other conditions requiring a speed reduction must be approved in writing by the Director of Traffic Engineering (contact MITís Traffic Engineering Branch at 204-945-3781).
WORK ZONE CONDITION / HAZZARD PRE-APPROVED SPEED LIMIT
Workers are located in close proximity to traffic (up to a maximum of 12m from an open traffic lane)
60 Km/h
A significant unprotected roadside hazard (e.g. excavation area) is located within the clear zone
70 Km/h
The conversion of a 4-lane divided highway to 2 lane/2 way operation
80 Km/h
A written record detailing the location, time of installation and time of removal of all regulatory speed reductions must be maintained by the traffic authority/contractor.
The use of reduced speed limit signs must be limited to those specific sections of highway where the pre-approved condition or hazard exists. They must NOT be used
throughout the project unless the pre-approved condition or hazard dictates. Speed limit signs must be removed immediately when the conditions change or hazards no longer exist.
MODIFICATIONS TO EXISTING TMPíS
Until an updated Workzone Traffic Control Manual is issued, the user of this manual will be required to modify the TMPís and STMPís contained herein to meet the new
regulatory requirements outlined in this amendment.
The following three examples are provided to illustrate typical changes required in a unilingual DCZ, in a bilingual DCZ, and in a non DCZ workzone. Sign spacing shall conform to the tables contained within the existing TMP.
To report deficiencies or other enquiries related to the modification of TMPís or STMPís should be directed to Traffic Engineering Branch (204) 945-3781

SPECIFICATIONS FOR TRAFFIC CONTROL
SCOPE
These Specifications and the Work Zone Traffic Control Manual govern operations pertaining to the regulation and guidance of traffic safely through or around the work.
DEFINITIONS
2.1 Work Zone Traffic Control Manual
A manual developed by the Department’s Traffic Engineering Branch intended to provide a single source for traffic control standards for use on Manitoba’s highways. All references in this Specification to signs, sign schedules and drawings shall be interpreted to mean those shown in the Work Zone Traffic Control Manual or any amendment to the Work Zone Traffic Control Manual issued by the Traffic Engineering Branch.
2.2 Work Zone
A work zone is an area of the highway with construction, maintenance, or utility work activities. A work zone is typically marked by signs, channelizing devices, barriers, pavement markings, and/or work vehicles. It extends from the first warning sign or flashing lights on a vehicle to the “Construction Ends” sign or the last temporary traffic control device. A work zone may be for short or long durations and may include stationary and mobile activities.
2.3 Work Area
A work area is located within a work zone and is defined as any portion of the highway on which the Contractor's staff and equipment are performing work and/or where a construction related hazard exists. There may be multiple work areas within a single work zone. Two or more work areas separated by less than one kilometre will be considered as a single work area.
2.4 Traffic Control Device
A traffic control device is any approved gateway assembly, sign, barricade, channelization device or other device placed upon, over or adjacent to a roadway, which is intended to regulate, warn, or guide road users.
2.5 Traffic Control Level
A traffic control level will specify the type and application of traffic control devices and workforce necessary to regulate traffic having regard to traffic volume, geometrics and type of work on the project.
Traffic control required on the project will be determined by the Engineer and identified in the bid items as Level I, II, III, IV or V.
2.6 Traffic Management Plan (TMP)
A Traffic Management Plan (TMP) is a detailed plan for the placement of all traffic control devices within the work zone. The typical TMP templates included in the Work Zone Traffic Control Manual shall be used as the basis for a project TMP on simple traffic control projects. For complex traffic control projects, a site specific TMP’s must be developed.
2.7 Designated Construction Zone
A Designated Construction Zone (DCZ) is a work zone where The Highway Traffic Act authorizes double fines for speeding whether or not there are workers/equipment present and whether or not there is a reduction in the maximum speed within the DCZ.
Traffic authorities and contractors working on their behalf establish and identify a DCZ by using the signage prescribed in the Designated Construction Zones Regulation.
GENERAL
3.1 Interference with Traffic
The Contractor shall not close the highway or reduce the width or number of traffic lanes available for traffic except as specified in the Contract or approved by the Engineer.
The Contractor shall at all times carry on the work in a manner that will create the least interference with traffic, consistent with the performance of the work.
Construction equipment shall not be parked in such a manner as to obscure or in any way block the road users' view of traffic control devices. Employees vehicles may only be parked on the roadway if they are being used in the performance of the work.
The Contractor shall keep the travelled way free of foreign objects such as spilled earth, rock, timber and other items that may fall from his transporting vehicles. Materials spilled by or dropped along or across any public travelled roadway, both within and outside the contract limits, shall be removed immediately.
The Contractor shall provide and maintain reasonable access to property fronting or in the vicinity of the work. Where temporary disruption of access is authorized by the Engineer, the Contractor shall make adequate arrangements with the affected property owners.
3.2 Traffic Management Plans
The Contractor shall prepare and submit a separate Traffic Management Plan (TMP) for each stage of planned construction operations. All TMP’s shall be reviewed and approved by the Engineer prior to the commencement of the project. The contractor shall ensure that copies of the TMP’s are available on site at all times.
Should planned construction operations change after the commencement of the project, the contractor shall prepare a new TMP reflecting the change. The new TMP shall be reviewed and approved by the Engineer prior to the commencement of that stage of work.
3.3 Regulatory Speed Reductions
Traffic Management Plans may include regulatory speed reductions within the work zone when a risk analysis indicates that they are required for the safety of workers and/or road users. Longer work zones may have multiple reduced speed areas coinciding with individual work areas of the project.
Where a risk analysis supports the need for a speed reduction, the Director of Traffic Engineering has granted blanket pre-approval for regulatory speed reductions for the following common work zone conditions and hazards. The Contractor shall seek the approval of the Engineer prior to introducing a regulatory speed reduction authorized under the blanket pre-approval.
All other conditions requiring a speed reduction must be approved by the Director of Traffic Engineering.
WORK ZONE CONDITION / HAZZARD PRE-APPROVED MINIMUM SPEED LIMIT
3.4 Placement of Traffic Control Devices
All Traffic control devices shall be placed in accordance with the approved Traffic Management Plan.
Non-portable sign and other fixed traffic control devices shall be installed prior to commencing work.
Portable signs and other temporary traffic control devices shall be positioned prior to commencing work in each work area and they shall be moved and maintained as the work progresses.
3.5 Maintenance of Traffic Control Devices
When the Contractor ceases operations due to darkness, weekends or weather conditions, or changes the method or sequence of operation, traffic control devices shall be checked and only those necessary to protect road users shall remain in place. During periods when they are not applicable, portable devices shall be removed from the roadway; non-portable devices shall be covered or removed.
Traffic control devices shall be monitored to ensure proper location, legibility and condition, and if necessary, shall immediately be properly repositioned, repaired or replaced.
3.6 Reflectivity
Signs, barricades and channelization devices shall be reflectorized to show the same color and shape by night as by day. The reflective surfaces shall be cleaned or replaced as frequently as necessary to provide full reflectivity. Reflectorized signs will be acceptable if they are clearly visible when illuminated with normal vehicle lights on high beam from a distance of 150 metres.
Reflectivity must meet or exceed ASTM Type IV except for the Flagperson Ahead Sign (MC-64) and the Flagperson paddle (MC-44A and MC-44B) which must meet or exceed ASTM Type XI – Fluorescent.
APPROVED EXTENT OF REDUCED SPEED ZONE
Workers are located in close proximity to traffic (up to a maximum of 12m from an open traffic lane) 60 Km/h 500m in advance of area where workers are active to 300m beyond area where workers are active A significant unprotected roadside hazard (e.g. excavation area) is located within the clear zone

Unless otherwise directed, the Contractor shall remove the gateway assembly if work is discontinued for the winter.
4.2 Signs
The Contractor shall provide signs as shown on the approved Traffic Management Plan . All signs used shall be in accordance with the Work Zone Traffic Control Manual, the Manual of Uniform Traffic Control Devices for Canada or Provincial Regulations.
Department construction and maintenance projects will include the use of bilingual highway construction signs (English/French) on all Provincial Trunk Highways and Provincial Roads that lie within the "Bilingual Signing Area" in Manitoba. Generally, all highway construction signs with verbal messages will be affected. Where applicable, bilingual signing requirements will be identified in the Special Provisions of the tender document.
Portable signs shall be placed on the roadway clear of normal vehicular traffic, stand vertically and be pinned or anchored so that wind gusts will not topple the sign. The bottom of the sign shall be at least 600mm above the surface of the road.
The bottom of non-portable signs shall be at least 1,500mm above the surface of the road. With the exception of Gateway Assemblies, the edge of signs shall be clear of the highway shoulder line by at least one metre, and shall be clear of the edge of curbed roadways by at least 300mm in urban areas and 600mm in rural areas.
Non-portable sign posts shall be wooden, capable of supporting the sign firmly at the required height and shall have a minimum nominal size of 100mm x 100mm.
In general, signs shall be positioned on the right-hand side of the road. When two or more adjacent lanes accommodate traffic travelling in the same direction, both non-portable and portable signs shall be positioned on both sides of the roadway.
Where bilingual signing is a requirement, the French sign shall be installed behind the English sign at a distance of approximately 30m.
4.2.1 Designated Construction Zone Signage
All projects on provincial highways lasting longer than four hours shall be signed as a Designated Construction Zone (DCZ).
The beginning of the DCZ shall be identified with the ‘Designated Construction Zone’ sign. This sign shall be affixed to the gateway assembly located at the start of the work zone unless otherwise directed by the Engineer. The sign shall be located so that drivers have an unimpeded view of the sign.
The end of a DCZ shall be marked with the ‘Construction Ends’ sign. This sign shall be affixed to the gateway assembly located at the end of the work zone unless otherwise directed by the Engineer. The sign shall be located so that drivers have an unimpeded view of the sign.
At least one ‘Speed Fines Double’ sign must be placed within a DCZ and be no more than 150m after the ‘Designated Construction Zone’ sign which marks the beginning of the DCZ.
Additional ‘Speed Fines Double’ signs may be placed within the DCZ to heighten driver awareness. The sign may also be used to mark a portion of road within the DCZ that intersects with another roadway.
Bilingual Traffic Signing Areas shall be signed in both official languages.
4.2.2 Construction Area Sign
The Construction Area sign shall be used in advance of work areas which are separated by more than 5 km from the Gateway Assembly or from other work areas.
For all projects with traffic control level II, III, IV, or V, Construction Area signs are to be installed at the intersection of every Provincial Trunk Highway or Provincial Road. Construction Area signs may be required at other intersecting roadways that enter onto the project. These other roadways will be identified in the Special Provisions.
4.2.3 Temporary Sign Stands
Temporary sign stands, when required, shall be supplied by the Contractor from the following recommended group:
• Flexmast Model PCC3648

The Contractor shall provide ballast to prevent movement of the drums by the wind. Drums shall be spaced in accordance with the approved Traffic Management Plan.
4.4.4 Traffic Cones
Traffic cones, when approved by the Engineer, may be used during daylight hours to guide or channel traffic through a work area.
4.4.5 Sequential Flashers
A sequential flashing traffic control device (sequential flasher) shall be used in conjunction with other traffic control devices to close a single lane on a multi lane highway. The Department will supply the sequential flasher for these lane closures.
The use of sequential flashers for any purpose other than lane closures on multi lane highways is subject to the approval of the engineer.
Where sequential flashers have been approved for a use other than lane closures on multi lane highways, the contractor may elect to rent the device from the Department if available, or they may be obtained from other sources providing they are equivalent in size, portability and visibility to the sequential flashers used by the Department.
Sequential flashers shall be located as shown on the approved Traffic Management Plan. In the event that a sequential flasher becomes inoperative, the Contractor shall ensure that adequate traffic control is maintained.
4.4.5 Sequential flashers rented from the Department will be charged for at the Department's standard
rental rate, and the rental will be deducted from progress payments.
The Contractor shall place, move and maintain sequential flashers supplied by or rented from the Department in accordance with written instructions obtained with each unit.
4.4.6 Rigid Channelization Devices
Rigid channelization devices such as concrete median barriers and Triton barriers may be required by the Engineer to channelize or separate traffic. When these types of devices are required, they will be supplied by the Department.
These devices shall be installed as shown on the approved Traffic Management Plan and in accordance with guidelines contained in the Work Zone Traffic Control Manual.
When “Triton” barriers are required to be in use during freezing temperatures, they shall be filled with a brine mixture (normally a 20% sodium chloride (salt), 80% water mixture). Where a brine mixture is required, the Department will supply the sodium chloride.
