Northern Expressway (Massachusetts)

As Northern Expressway which is 27.9 mi ( 44.9 km ) denotes long section of Interstate 93 north of the city of Boston, Massachusetts in the United States to the state border to New Hampshire.

History

The Northern Expressway was built from Medford, starting to the border of New Hampshire 1956-1963. From 1965 to 1973 he was extended through Somerville and Charlestown to the Central Artery and U.S. Highway 1 in Boston. Since the street was already under construction, she received an exemption for 1970 adopted moratorium on the expansion of existing highways within the Massachusetts Route 128

The southern end of Interstate 93 was originally located in Cambridge, where the road was supposed to meet the planned Inner Belt ( Interstate 695). This bypass was never built, and also were the plans that lead to Interstate 95 through Boston, discarded. Mid-1970s was the I-95 guided along Route 128 and I-93 for another 18 mi (29 km ) along the Central Artery and on over the Southeast Expressway to the Braintree and along the former course of Route 128 to the connection extended to I- 95 in Canton.

In order to reduce traffic congestion during rush hours, is allowed between exits 41 and 47/48 at certain times driving on the emergency lane on I- 93. Actually, however, this provision does little to reduce traffic congestion lengths and is viewed critically by the Massachusetts State Police, because by so blocked emergency lane, emergency vehicles have no unobstructed ride and can not respond quickly to emergencies.
