Common Reasons Traffic Control Plans Get Corrected

The issues that most often lead to agency comments and corrections on a traffic control plan, and how to avoid them.

Published June 24, 2026

When a traffic control plan is submitted for review, agencies often return comments or corrections before approving it. Many of these come from the same recurring issues.

This article covers the common reasons plans get corrected so teams can catch them before submitting.

Missing or Incomplete Pedestrian Routing

A frequent comment is that the plan does not fully address how people on foot get past the work, especially accessible routing when a sidewalk is affected. Plans that leave this out are commonly sent back.

Wrong Closure or Device Details

Plans get corrected when the closure type, taper length, or device spacing does not fit the road or its speed. These details are checked against the conditions at the location.

Mismatched Jurisdiction or Conditions

Submitting to the wrong agency for the roadway, or not reflecting that agency's standards and conditions, leads to corrections. In Southern California, for example, state highway work follows Caltrans requirements while city streets follow the city's.

How to Avoid Corrections

Confirm the correct agency for the roadway before submitting.
Include complete, accessible pedestrian routing.
Match closure type, tapers, and spacing to the road and speed.
Address all conditions and prior comments before resubmitting.
