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.
