What Is a Pedestrian Detour?

A pedestrian detour directs people on foot around a closed sidewalk or walkway using an alternate path, often across the street using existing crossings. It is used when a usable route cannot be kept past the work. The detour is marked with signs and barricades so people know where to go before they reach the closure.

Why It Matters

A clear detour keeps pedestrians out of travel lanes and away from the work. Without one, people may improvise unsafe routes.

A good detour is also accessible, so that people using wheelchairs can follow it with usable crossings and curb ramps along the way.

Where It Shows Up in the Field

Pedestrian detours show up where a sidewalk is fully closed and no path can be maintained alongside the work. They are common in built-up Southern California corridors with continuous sidewalks.

In the field, the detour connects logically to existing crossings so people are not led to a dead end.

Common Mistakes

Sending pedestrians to a crossing that is itself closed or blocked.
Failing to sign the detour far enough upstream.
Creating a detour that is not accessible to people using wheelchairs.
Assuming people will cross mid-block instead of providing a real route.

What to Check Before Work Begins

That the detour uses existing, usable crossings.
That signs guide people before they reach the closure.
That curb ramps and crossings along the detour are accessible.
Whether the permit specifies how the detour must be handled.

Frequently Asked Questions

When is a pedestrian detour required?

A pedestrian detour is generally used when a sidewalk is closed and a usable path cannot be kept past the work. The exact requirement depends on the conditions, the approved plan, and the governing agency.

Does a pedestrian detour need to be accessible?

Yes. A detour should work for people of all abilities, including those using wheelchairs, which means usable crossings, curb ramps, and a clear, continuous path from start to finish.

Where should pedestrian detour signs be placed?

Detour signs go far enough upstream that people see them before reaching the closure, not at the closure itself, so they are not forced to backtrack.
