If an alternate route affects a county or another city, the city should obtain written consent from the affected county or city.

Weight and size carrying capability of the alternate route should be reasonably comparable. Also, the route should not be unreasonably longer than the original route. It should not be confusing to follow and should be selected so as not to jeopardize public safety. All truck routes should be on the State highway system.

The city assumes all responsibility for the route, including enforcement and any other legal matters.

Any route involving the Interstate System should be approved by the Federal Highway Administration (FHWA). The TxDOT Traffic Operations Division (TRF) coordinates the necessary approval with the FHWA.
