Travel directions

The US 1 freeway in Chelsea, on the north side of Boston.

Between Pawtucket and South Attleboro, US 1 crosses the border with Rhode Island and Massachusetts as a secondary highway. The road will then run as a 4-lane main road parallel to Interstate 95 to the north. It passes through places like Attleboro and Norwood, before ending on Interstate 95 at Dedham. The road then follows the route of I-95/I-93 eastwards, then follows Interstate 93 to downtown Boston. North of the Zakim Bridge, the road curves 270 degrees under I-93, then becomes a freeway itself. US 1 crosses Boston Harbor via the double-deck Tobin Bridge toll bridge. The road has 2×2 lanes here. The highway then has 2×3 lanes and winds through the suburb of Chelsea. This section is first called the Adamski Memorial Highway, and later the Northeast Expressway. One passes by Revere, and the highway section ends in the suburb of Saugus. The road then runs northeast as six-lane Broadway, crossing I-95 twice in quick succession at Peabody. The road then turns to the northeast as a secondary main road, almost straight. US 1 crosses the New Hampshire border at Salisbury Plains.


In Boston, US 1 forms the Northeast Expressway, a short highway to the suburb of Revere. This is a remnant of older plans to run I-95 not around, but through Boston, as is customary in the United States. The Tobin Bridge opened to traffic on February 27, 1950. In 1956 and 1958, the rest of the Northeast Expressway opened through Chelsea and Revere. The highway was numbered as I-95 between 1955 and 1973.

US 20 is a US Highway in the US state of Massachusetts. The road forms an east-west route from the New York State border through Pittsfield, Springfield, and Worcester to Boston. US 20 is 247 kilometers long in Massachusetts.

Travel directions

US 20 crosses the state of Massachusetts from east to west and is the only US Highway to do so. The route is largely parallel to Interstate 90, making US 20 itself less important. Most east of Springfield is a 2×2 lane divided highway that runs through urban areas around Worcester and the Boston metropolitan area. US 20 is of great local importance as an access road. US 20 usually runs no more than 9 miles from I-90, the greatest distance being in the western part of the state, where US 20 winds through Pittsfield.


Created in 1926, US 20 has always been the primary highway for traffic within the state of Massachusetts, as the route connects all of the state’s major cities. Partly because of this, US 20 has been widened to a four-lane road since the 1930s and suburbanization quickly increased along the corridor. Because US 20 was not suitable for through traffic due to the many buildings along the road, a replacement was planned from the 1940s in the form of the Massachusetts Turnpike. This toll road opened on May 15, 1957parallel to US 20 between the New York border and the western suburbs of Boston. In 1964 and 1965, the last section of the toll road opened in Boston, completely eliminating the throughput of US 20. The turnpike has since been numbered as part of Interstate 90.

Traffic intensities

In 2011, 5,000 vehicles drove daily at the New York border and 23,000 vehicles on the double-numbered US 7 south of Pittsfield. Continuing as far as the Springfield area, between 2,000 and 5,000 vehicles ran, rising to 20,000 vehicles in West Springfield and 43,000 vehicles on the Connecticut River bridge in Springfield. East of Springfield, intensities range from 7,000 to 15,000 vehicles to Worcester, rising to 26,000 vehicles east of Worcester and 16,000 vehicles west of Marlborough. In the western suburbs of Boston, there were 13,000 to 30,000 vehicles and 11,000 to 30,000 vehicles in Cambridge. The last part in Boston has 28,000 vehicles.
