Bill > HB1785

This bill requires New Hampshire to update exit numbering on all Tier I highways (except Interstate 393) to conform with the United States Department of Transportation's Manual on Uniform Traffic Control Devices (MUTCD). Specifically, exit numbers will be based on actual highway mileage using the Department of Transportation's linear referencing system, which means exits will be numbered according to their precise mile marker location. The Department of Transportation will have until 2038 to complete this signage replacement project, which involves adding overlay panels to existing signs to show the new mile-based exit numbers. The estimated implementation cost is approximately $2.4 million, with roughly 35% funded by Turnpike funds and the remainder potentially coming from federal highway funding. The bill affects multiple highways including Interstate 93, Interstate 89, Interstate 293, Interstate 95, the FE Everett Turnpike, Spaulding Turnpike, NH Route 101, and Raymond Wieczorek Drive, covering a total of 142 interchanges and 291 exit ramps. The new exit numbering system will help standardize highway signage and make navigation more intuitive for drivers by directly correlating exit numbers with highway miles.
