Dual and Triple Routing on State Trunklines
The Reflective Systems Unit in reviewing the state trunkline system has discovered a substantial number of dual and some triple routing on both the free access and limited access system. We will be contacting the Trunkline Numbering Committee in an attempt to reduce as much of this unnecessary routing as possible in an attempt to avoid driver confusion and save funds.
Attached is a list of segments that you should review, revise, and return to us by November 5, 1982, with any comments concerning this matter.
