Mass DOT Exit Number Information
Posted on: April 22, 2021 - 4:07pm
The Massachusetts Department of Transportation (MassDOT) is converting all exit numbers on freeways to a milepost-based numbering system, per Federal Highway Administration (FHWA) requirement. Currently, interstates and freeways in Massachusetts utilize a sequential exit numbering method. MassDOT has committed to the implementation of mile-based with construction scheduled to begin in Fall 2020.
