Mass Highways Change Exit Numbers; What’s Your New Exit?
The Massachusetts Department of Transportation says its exit renumbering project, which was announced last year, will begin next month, with current exit numbers on most highways in Massachusetts switching to mileage-based exit numbers.
The exit numbers are set to roll out in October and are being changed by MassDOT to comply with federal highway mandates, which require mile-based exit signs. Massachusetts is one of three states that have not yet begun any sort of conversion to the mileage-based system. Delaware and New Hampshire are the other two states.
Heading down the Mass Pike to New York City? You'll be getting off Exit 78 to connect with Interstate 84 instead of Exit 9. Heading to Gillette Stadium in Foxborough by way of Interstate 95? Get used to getting off at Exit 19 instead of Exit 9.
