MICHIGAN
DEPARTMENT OF TRANSPORTATION
SPECIAL PROVISION
FOR
TEMPORARY PEDESTRIAN PATH
COS:CRB 1 of 2 APPR:MRB:CAL:06-25-21
FHWA:APPR:06-28-21
a. Description. This work consists of furnishing, installing, maintaining, and removing a
temporary pedestrian path as identified in the proposal or on the plans. Temporary pedestrian
paths, or segments thereof, will be repaired or replaced as directed by the Engineer

b. Materials. Provide materials to construct a temporary pedestrian path in accordance with
the contract, the Public Rights-of-Way Accessibility Guidelines (PROWAG), the MMUTCD, as
directed by the Engineer, and the following requirements:
1. Ensure the materials used to construct the temporary pedestrian path yields a
continuous hard surface that is firm, stable and slip resistant. Ensure the path does not warp,
buckle or otherwise become uneven, and materials support the weight of pedestrians as well
as motorized scooters and wheelchairs. Suitable materials to construct the path include
asphalt materials, Oriented Strand Board (OSB), plywood, dimensional lumber, reclaimed, or
other as approved by the Engineer. Compacted soils, aggregate and sand are prohibited

2. If asphalt materials are not used to construct the path, provide an antiskid coating, or
surface treatment as directed by the Engineer

c. Construction. Construct the temporary pedestrian path in accordance with PROWAG,
the MMUTCD, the contract, the direction of the Engineer, and the following:
1. Ensure the useable surface of the path is a minimum of 48 inches wide. The maximum
cross slope for the path is 2 percent. The path, including transitions to the adjacent surface
at both ends, must be free of vertical discontinuities greater than 1/4 inch. Eliminate any
vertical discontinuities greater than 1/4 inch up to 1/2 inch or bevel with a slope not steeper
than 1:2. If a vertical discontinuity greater than 1/2 inch or a running slope greater than 1:20
occurs on the project, a Temporary Pedestrian Ramp (paid for separately) is required

A. Ensure an anti-slip surface treatment is applied to the surface of the path, if not
constructed with asphalt materials, as directed by the Engineer

B. If the surface of the path is constructed from OSB, plywood, or dimensional lumber
securely connect all sections with appropriate fasteners to ensure a continuous, uniform,
and flat surface

C. Ensure the temporary pedestrian path includes passing spaces at intervals of 200
feet maximum. The passing spaces are to be of the same material as the rest of the
temporary pedestrian path. Dimension the passing spaces with a minimum width of 60
inches and minimum length of 60 inches. Passing spaces are not required if the path is
already 60 inches wide

COS:CRB 2 of 2 06-25-21
2. Ensure all debris and construction material is cleared from the path throughout its use

Ensure snow and ice is removed; the use of an approved de-icing agent may be required

3. Repair or replace the path, or segments thereof, if it becomes uneven, unstable, or
displaces due to weather events, construction activities, or other causes as directed by the
Engineer

4. Following the use of the temporary path, the Contractor must remove and dispose all
materials used to construct the path, and restore the area as directed by the Engineer

d. Measurement and Payment. The completed work, as described, will be measured and
paid for at the contract unit price using the following pay item:
Pay Item Pay Unit
Pedestrian Path, Temp ...............................................................................................Foot
Pedestrian Path, Temp will be measured along the centerline of the path. Pedestrian Path,
Temp includes all costs related to installation, maintenance, restoration, and removal of the path
and disposal of all associated materials throughout the life of the contract. Temporary passing
spaces are considered a part of the pedestrian path and are included in this pay item

C. Ensure the temporary pedestrian path includes passing spaces at intervals of 200 feet maximum. The passing spaces are to be of the same material as the rest of the temporary …
