Interstate 93 begins in the south at exit 12 of I-95 in Canton, Massachusetts. I-93 begins co-signed with U.S. Route 1 North. At this junction, I-95 North heads to the northwest (co-signed with U.S. Route 1 South, as well as Route 128, which begins at the interchange). to serve as the beltway around Boston, while I-95 South runs by itself southwest through Boston's southeastern suburbs towards Rhode Island.
The first few miles of I-93 run almost due east through Boston's southern suburbs, passing through Canton and Randolph. In Randolph, I-93 meets the northern end of Route 24 (Fall River Expressway/AMVETS Memorial Highway) at Exit 4. I-93 continues east into Braintree, interchanging with Route 3, the major freeway linking Boston to Cape Cod, at Exit 7. Route 3 North joins I-93 and US-1, and the highway turns north towards Boston.
Signs in the Financial District of Boston, Massachusetts point towards Downtown Crossing, Chinatown, Interstate 93, and Interstate 90.Upon turning northward, the highway is known as the Southeast Expressway before reaching the city itself. Upon entering the city, the highway is known as the Central Artery, and passes beneath downtown Boston. A major intersection with the Massachusetts Turnpike/Interstate 90 (Exit 20) takes place just south of downtown Boston. After the massive interchange, motorists use the Thomas P. O'Neill Jr. Tunnel to travel underneath the city and then use Zakim Bunker Hill Bridge to cross the Charles River. Two exits are located in the tunnel, where the speed limit is a mere 45 miles an hour. Route 3 leaves the Artery just before the Zakim bridge via Exit 26, and U.S. Route 1 leaves the Artery just after the bridge, via Exit 27 (no southbound access). From Boston through the rest of Massachusetts, Concord appears as the control city on northbound overhead signs. The Artery ends as I-93 continues north out of the city.
I-93 continues through the northern suburbs of Boston, coming to a second intersection with Interstate 95. Bostonians traveling north can either change over to I-95 north to eventually reach Maine, or remain on I-93 towards New Hampshire. Farther north, in Andover, I-93 meets I-495, providing access to Worcester to the southwest and New Hampshire's seacoast region to the northeast. Just south of the state line, I-93 crosses the Merrimack River into Methuen, where it interchanges with Route 213, a connector between I-93 and I-495. I-93 then crosses into New Hampshire.
In all, I-93 has 48 numbered exits in Massachusetts, although several numbers are skipped in and near Boston. Exit 48 in Methuen, just before the New Hampshire state line, is the highest-numbered exit along the entire route. Due to the highway being one of the two major Interstates that enter Boston directly (Interstate 90 is the other), nearly the entire length of the highway in Massachusetts carries four lanes in each direction and is almost always very busy.
