The '''Sumner Tunnel''' is a road [[tunnel]] in [[Boston, Massachusetts|Boston]], [[Massachusetts]], United States. It carries traffic under [[Boston Harbor]] in one direction, from [[Logan International Airport]] and [[Massachusetts Route 1A|Route 1A]] in [[East Boston]]. The tunnel originally deposited traffic at the west side of the [[North End, Boston|North End]], but with the completion of the [[Big Dig (Boston, Massachusetts)|Big Dig]], it was modified to have two exits. One exit connects to [[Interstate 93|I-93]] northbound and downtown Boston (Government Center) near [[Haymarket (MBTA station)|Haymarket Station]]. The other exit connects to [[Storrow Drive]] and Nashua St., connecting [[Cambridge, Massachusetts|Cambridge]] via [[Massachusetts Route 28|Route 28]]. Traffic headed for I-93 southbound and the [[Massachusetts Turnpike]] ([[Interstate 90|I-90]]) westbound is normally routed to the [[Ted Williams Tunnel]]. It is managed by the [[Massachusetts Department of Transportation]].<ref name=":0">{{Cite web |title=Close-Out Audit of Agencies and Authorities Combined into the Massachusetts Department of Transportation |url=https://www.mass.gov/doc/close-out-of-agencies-and-authorities-combined-into-the-massachusetts-department-of/download |access-date=July 3, 2024 |website=Commonwealth of Massachusetts: Office of the State Auditor}}</ref>
