The route travels {{convert|136|mi|km|abbr=on}} generally west to east, entering Massachusetts at the New York state line in the town of [[West Stockbridge, Massachusetts|West Stockbridge]], and passes just north of [[Springfield, Massachusetts|Springfield]], just south of [[Worcester, Massachusetts|Worcester]] and through [[Framingham, Massachusetts|Framingham]] before terminating near Logan International Airport in Boston.<ref>{{cite web |title=Interstate 90 |url=http://www.interstate-guide.com/i-090.html |website=interstate-guide.com |publisher=AARoads |access-date=June 10, 2015}}</ref> Other major interstates include [[Interstate 91 in Massachusetts|I-91]], which travels generally north and south along the [[Connecticut River]]; [[Interstate 93 in Massachusetts|I-93]], which travels north and south through central Boston, then passes through [[Methuen, Massachusetts|Methuen]] before entering New Hampshire; and [[Interstate 95 in Massachusetts|I-95]], which connects [[Providence, Rhode Island]] with Greater Boston, forming a partial [[beltway|loop]] [[Concurrency (road)|concurrent]] with [[Massachusetts Route 128|Route{{spaces}}128]] around the more urbanized areas before continuing north along the coast into New Hampshire.<ref>{{cite news |first1 = David |last1 = Montgomery |first2 = Josh |last2 = White |newspaper = [[The Washington Post]] |title = 128 Cars, Trucks Crash in Snow on I-95 |date = February 23, 2001 |page = A1 }}</ref>

[[Interstate 495 (Massachusetts)|I-495]] forms a wide loop around the outer edge of Greater Boston. Other major interstates in Massachusetts include [[Interstate 291 (Massachusetts)|I-291]], [[Interstate 391 (Massachusetts)|I-391]], [[Interstate 84 in Massachusetts|I-84]], [[Interstate 195 in Massachusetts|I-195]], [[Interstate 395 in Massachusetts|I-395]], [[Interstate 290 (Massachusetts)|I-290]], and [[Interstate 190 (Massachusetts)|I-190]]. Major non-interstate highways in Massachusetts include [[United States Numbered Highways|U.S. Routes]] [[U.S. Route 1 in Massachusetts|1]], [[U.S. Route 3 in Massachusetts|3]], [[U.S. Route 6 in Massachusetts|6]], and [[U.S. Route 20 in Massachusetts|20]], and state routes [[Massachusetts Route 2|2]], [[Massachusetts Route 3|3]], 9, [[Massachusetts Route 24|24]], and 128. A great majority of interstates in Massachusetts were constructed during the mid-20th century, and at times were controversial, particularly the intent [[Southwest Corridor (Massachusetts)|to route I-95 northeastwards from Providence, Rhode Island, directly through central Boston]], first proposed in 1948. Opposition to continued construction grew, and in 1970 Governor [[Francis W. Sargent]] issued a general prohibition on most further freeway construction within the I-95/Route 128 loop in the Boston area.{{sfn|Brown|Tager|2000|pp=283–284}} A massive undertaking to bring I-93 underground in downtown Boston, called the [[Big Dig]], brought the city's highway system under public scrutiny for its high cost and construction quality.<ref name=BigDig1/>
