The road was initially planned to start in
Lowell at US-3 at a point between exits 81C and 84 (old 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, 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 (which at this time was known as "Relocated Route 113") 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. ==Exit list==
