Lexington is located off Exit 14 on Interstate 95, about 30 minutes away from downtown Boston. Approximate distances from other major Northeastern cities are as follows: New Bedford, Massachusetts - 65 mi/100 km; Providence, Rhode Island - 50 mi/80 km; Manchester, New Hampshire - 50 mi/80 km; New Haven, Connecticut - 130 mi/200 km; Portland, Maine - 110 mi/170 km.
Visitors from farther away should fly into Boston's Logan International Airport, which offers flights to all major cities throughout the US as well as Canada, Mexico and overseas. However, there are often not enough parking spaces in the town center during the summer. It takes about 45 minutes to get to Lexington from the airport; taxis can be found outside the baggage claim terminals and charge a flat per-mile fee; a list of such fees to cities outside the Boston metropolis is posted at the stand.
Public transportation is also available from Boston to Lexington. One option is to take the Silver Line bus to South Station and transfer to the Red Line. From there, go to the Alewife stop (the northern terminus) and take either the #76 or #62 bus to Lexington. The other option is to take the airport shuttle directly to the subway's Blue Line and make your way to North Station. From there, the Fitchburg-bound commuter rail stops at several towns adjacent to Lexington (though none in the city itself) such as Concord, Belmont and Lincoln.
A more adventurous way to get to Lexington is to bike the 11 miles on the Minuteman Bikeway. The trail starts at Alewife Station in Cambridge (just north of Boston) and ends at the Depot Park in Bedford.
