Expect your GPS to sound a bit different when approaching Dartmouth from the highway this October. Beginning later in the month, exit signs along I-195 will be changed to a mile-marker based system as part of the Massachusetts Department of Transportation Exit Renumbering Project. 

As required by the Federal Highway Administration, all MassDOT-owned highways will soon feature mile-based exit numbers instead of the sequential system currently in place. Whatever the mile number is nearest to the exit will become the number on the sign.

In Dartmouth, exits 11 and 11 A/B will be changed to 19 and 19 A/B, while exits 12 and 12 A/B will now become 22 and 22 A/B. 

90% of the project’s funding comes from federal funding, with the other 10% coming from state highway funds. 

According to MassDOT, the new system “allows drivers to determine distances to destinations” and “improves reporting of highway incidents, resulting in better navigation of emergency services.”
