5.03 Detours
5.03.01 Pedestrian
Pedestrian detour routing or temporary pathways should be considered based upon the level of impact. To be effective, pedestrian detours need to be clear and concise. Using existing pathways, ramps, and crosswalks is preferred; however, it may be necessary to construct temporary facilities.
With a temporary pedestrian facility consider the following to determine if the proposed plan is appropriate:
- Number and demographics of pedestrians
- Environmental Clearance Requirements (Section 5.02.A) are satisfied
- Roadway ADT
- Crosswalk configuration
- When possible, avoid the use of non-signalized crosswalks.
Temporary facilities should be a minimum of 4 feet wide, however, 5 feet is desirable. If the temporary facility sidewalk is bi-directional and 4 feet wide, a 5 x 5 foot passing space is required for every 200 feet of length.
The temporary facility must be designed such that ADA compliant accessibility is provided, at minimum, to the same level as the existing facility. To the extent practical, it is recommended to design temporary facilities to full ADA standards. If additional guidance is required for complex location contact the WZDE for guidance.
Alternate pedestrian routes should be smooth and level. The use of a smooth, firm, stable, slip resistant, and continuous hard surface (compacted soils, aggregate and sand are not to be used) is required to provide an acceptable temporary pedestrian route. For example special provisions, contact the WZDE.
Physical barriers need to be provided to prevent pedestrians from entering the work area. Pedestrian channelizing devices or pedestrian barrier with fence may be used for increased protection.
If a covered pathway is used to protect pedestrians from overhead work, 5 footcandles (54 lux) of illumination are recommended.
In the event of a full bridge closure, when a practical or alternate pedestrian route option does not exist, other mitigation measures should be considered. Such measures include the use of temporary structures and licensed transportation shuttles to transport pedestrians around the closure.
Where there is evidence of pedestrians but no pedestrian facilities (aka: a goat path), the route may be closed without a detour.
Pedestrians should not be temporarily rerouted across railroad tracks unless there is an existing pedestrian crossing. If unavoidable, contact MDOT’s WZMU.
Informational signs or other suitable devices should be used to provide reasonable notice to pedestrians, including the type and duration of construction activities. PCMS should only be used for pedestrian detours with substantial pedestrian traffic volumes. For example, the placement of a PCMS for pedestrians at a stadium should clearly indicate that the message is for non-motorized traffic.
