states that traffic control plans shall address pedestrian traffic during individual phases of construction and operation. The Part 6 provides guidance on the planning and design of temporary traffic control (TTC) which states: “The needs and control of all road users (motorists, bicyclists, and pedestrians within the highway, or on private roads open to public travel … including persons with disabilities in accordance with the through a TTC zone shall be an essential part of highway construction, utility work, maintenance operations, and the management of traffic incidents.” Refer to the and the WZ (BTS-2) standard for more information on specific traffic control measures for pedestrians in work zones. depicts an example layout for a sidewalk detour.

Construction activities that affect pedestrian facilities or connectivity to those facilities must provide and maintain an accessible detour. In some cases, this route may continue to be along the roadway in question, (e.g., creating a temporary walking path by placing appropriate barricades, reflectorized drums, and signage to reallocate roadway space during closure of a sidewalk.) Walkways must be clearly identified, accessible, and free from hazards. Barricades separating the pedestrian route from motor vehicle traffic must be of sufficient strength to withstand intrusion by an impacting vehicle. On higher-speed roadways, continuous, temporary pre-cast concrete barriers are recommended.

It is preferred to maintain the pedestrian route on the same side of the street when a sidewalk is closed. Completely closing a sidewalk for construction and rerouting pedestrians to the other side of the street is another, less desirable option. In the event pedestrians are rerouted to the other side of the street, the street crossing should be located at an intersection, existing crosswalk, or other suitable and safe location. Access to pedestrian pushbuttons must be maintained during sidewalk closures.

Other cases may completely close a roadway that provides pedestrian access to destinations in areas of high pedestrian activity, (e.g., the closure of a bridge or underpass across a freeway.)

Where pedestrian detours are implemented, appropriate signing must be provided in advance of decision points to allow pedestrians to make appropriate decisions about navigating the space. also requires that motion activated signs that convey the same information as the printed sign be provided to ensure that pedestrians with vision disabilities are provided the guidance needed to navigate the temporary pedestrian route.

Where transit stops are disturbed as part of construction or maintenance activity, an alternate accessible transit stop must be provided.

Refer to Section 2D.50 for additional guidance on the placement of pedestrian oriented wayfinding signage.
