Avoiding Unnecessary Concurrent Routes

Concurrent routes should be avoided and their number reduced where possible.
EXAMPLE: A state highway joins a US highway and runs concurrent with it into Town X. The US highway continues through the town, but the state highway ends at the town (see Figure 7-1). The concurrent signing should be eliminated, terminating the signing of the state highway where it joins the US highway.
Example of unnecessary concurrent signing.Signing for SH 65 should terminate at junction with US 83. (click in image to see full-size image)
