carrying US 1 over the
Mystic River in Connecticut US 1 in Connecticut largely parallels
I-95 and has many interchanges with it. The route passes through each city and town of Connecticut bordering the
Long Island Sound (in addition to the town of
Orange). From
Greenwich to
Branford, US 1 is mostly a four- or six-lane principal arterial road (with some two-lane sections in dense areas). From Branford to
Stonington, US 1 it a two- or four-lane minor arterial road. US 1 is known as Boston Post Road or Post Road for the majority of its length, but it also encompasses other local street names. The route is known as Putnam Avenue in Greenwich; Tresser Boulevard, West Main Street, and East Main Street in
Stamford; Connecticut Avenue in parts of
Norwalk; Boston Avenue in parts of
Bridgeport; and New London Road in parts of
Groton. In Stonington, the route is known as Stonington Road, South Broad Street, and West Broad Street. US 1 is also known as Main Street in Branford and
Clinton. Two sections of US 1 have been designated as
scenic roads by the state of Connecticut. A 2.34 mile section in
Madison between Neck Road and Lover's Lane (designated in 2008) and a 0.96 mile section in
Old Lyme between the
Lieutenant River and Griswold Avenue (designated in 2012).
Overlap with I-95 US 1 is
concurrent with I-95 in two sections, both of which are river crossings. The western concurrency is between exits 68 and 70 from
Old Saybrook to
Old Lyme, where the two routes cross the
Connecticut River via the
Raymond E. Baldwin Bridge. The eastern concurrency is between exits 83 and 85 from
New London to
Groton, where the routes cross the
Thames River via the
Gold Star Memorial Bridge. US 1's two other major bridge crossings closely parallel the I-95 crossings of those rivers. The
Washington Bridge over the
Housatonic River, connecting
Milford and
Stratford, as well as the
Tomlinson Lift Bridge over the
Quinnipiac River in
New Haven, are a short distance away from I-95's
Moses Wheeler and
Pearl Harbor Memorial bridges, respectively. US 1 also forms a
frontage road for I-95 in parts of
Fairfield, Stratford, and
New London. ==History==
