Route 24 is a 40.91-mile-long (65.84 km) freeway south of Interstate 93 (I-93) in southeastern Massachusetts, linking Fall River with the Boston metropolitan area.

It begins in the south in Fall River at the border with Tiverton, Rhode Island, and runs north to an interchange with I-93/US 1 in Randolph.

The highway continues north through the city of Brockton and into Randolph, where Route 24 ends at a split junction with Interstate 93.

The route is officially 40.9 miles in length, however, mileposts continue up to 41.2 on the Exit 21B ramp to I-93 south.

The project would require major upgrades to 11 interchanges and minor work on 6 others, and the plan was halted due to high costs.

The Southeastern Regional Planning and Economic Development District (SRPEDD) endorsed a similar proposal the month before which if built, according to a MassHighway official, would have been signed as an extension of I-93.

[2] This proposal too was eventually tabled due to high costs, especially those projected for reconstruction of part of the highway south of Interstate 495.
