Interstate 291 (Massachusetts)とは 意味・読み方・使い方

Interstate 291 (abbreviated I-291, formerly known as the Springfield Expressway) is a 5.44-mile (8.75 km) connector highway in Massachusetts that links Interstate 91 in downtown Springfield with Interstate 90 (the 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 Mass Pike at its northeastern terminus. Getting onto the Pike from I-291 is straightforward, but getting from the Pike to I-291 requires a left turn at a stop light. I-291 travels directly through highly-populated areas of Springfield, and passes under several overpasses. From its southwestern terminus to exit 5A, Interstate 291 is also U.S. Route 20.
