Route 213 begins in the west as an offshoot of I-93 at its northernmost exit in Massachusetts, Exit 48, just south of the New Hampshirestate line. It begins by traveling to the east for less than a half mile before meeting Route 28 at Exit 2. Route 28 southbound provides access to the downtown area which Route 213 bypasses. Route 28 northbound parallels I-93, crossing into Salem, New Hampshire and becoming New Hampshire Route 28 after approximately one-half mile. Route 213 continues eastward for about another mile before interchanging with Route 113, with access between Route 113 and westbound Route 213 facilitated by nearby Howe Street. Another half mile or so to the east, Route 213 interchanges with Route 113 again, via a short connecting road to Exit 4. This exit provides nearby access to The Loop. Route 213 continues a short distance to the east, crossing underneath Route 113 before ending at an interchange with I-495.
History
The road was initially planned to start in Lowell at US-3 at a point between exits 31 and 32. From there, it was to have run north, crossing the Merrimack River roughly at the site of the current Rourke Bridge. It would then continue north through a portion of the Lowell-Dracut State Forest before turning east through until crossing I-93 in Methuen and ending at I-495. However, environmental regulations, a growing opposition in both Lowell and Dracut, and a projected insufficient demand for the road caused the state to permanently kill the portion of the highway between US-3 and I-93. The expressway between I-93 and the current Exit 3 interchange was completed on September 11, 1962, when it was ceremonially named the Albert Slack Memorial Highway. The eastward extension to I-495 was completed in 1964, and Massachusetts Department of Public Works officially designated the road as Route 213. State officials unsuccessfully submitted for inclusion of Route 213 in the Interstate Highway System in 1970, in an attempt to gain federal funding for the project. The submission was rejected by the Federal Highway Administration. Route 213 was officially designated as the Loop Connector in October 2000 by the Massachusetts legislature. Interchanges along Route 213 were to be renumbered to mileage-based numbers under a project scheduled to start in 2016; however, this project was indefinitely postponed by MassDOT. On November 18, 2019, MassDOT announced that this route will not be changing the exit numbers, due to the route's short length.
