Interstate 291 (I-291), also known as the Springfield Expressway,^[3] is a 5.44-mile (8.75 km) auxiliary Interstate Highway in Massachusetts that links I-91 in downtown Springfield with I-90 (Massachusetts Turnpike) in Chicopee. I-291 is roughly a northeast–southwest highway. It merges with I-91 at its southwestern terminus, via a flyover. The road meets the turnpike at its northeastern terminus. Getting onto the turnpike from I-291 is straightforward, but getting from the turnpike to I-291 requires a left turn at an at-grade traffic signal. I-291 travels directly through highly populated areas of Springfield and passes under several overpasses. From its southwestern terminus to exit 5A, I-291 is concurrent with US Route 20 (US 20).

I-291 is only 22.4 miles (36.0 km) from Interstate 291 in Connecticut, and there are no intervening Interstate Highway interchanges between them.
