New Highway Exit Sign Numbers Revealed

It's going to be a couple years before your highway exit gets a new number, but the Massachusetts Department of Transportation is telling you which digits to expect where. The state unveiled a website that says which new numbers will be assigned to highway exit signs in an upcoming statewide change.

The website Newmassexits.com has an interactive map showing which exits will be changed and what they will be changed to. It also has a list for major interstates, such as I-90, I-93 and I-495.

The numbers will be based on mileage, bringing Massachusetts into compliance with federal mandate and eliminating the risk of losing federal funds. Federal funds in this case will pay for 90 percent of the cost of changing sign numbers.

The changes will come "route-by-route," MassDOT said. They will begin in Western Mass. and move east, and on individual routes will change east to west or north to south.

The signs will begin going up two summer, but it could be much longer than that until it gets to the Boston area.

The old exit signs will remain up for two years after the replacement signs are installed, allowing for people to get used to the change.
