Route 57 is a 45.42-mile-long (73.10 km) east–west Massachusetts state route that runs from Monterey to Agawam. The eastern 5.0 miles[2] (8.1 km) in Agawam is a freeway that runs from Route 187 to the route's eastern terminus at U.S. Route 5.[3]
Route description
Eastbound entering Sandisfield
The route begins in Monterey, at its intersection with routes 23 and 183.[4] The section from there to New Marlborough (which is a concurrency with Route 183) primarily takes a southeastern path that passes several stretches of farmland.[3] In New Marlborough, Route 57 splits from Route 183 and follows a mainly easterly route with frequent curves, passing more farmland.[3] During this stretch, there is a brief concurrency with Route 8 in Sandisfield to cross the Farmington River's west branch.[5]
Route 57 (which was formed by 1930[1]) initially went from Southwick to West Springfield.[1] It was extended to Sandisfield in the mid-1930s and Monterey in the late 1940s.[1]
Construction on the freeway portion began in 1958,[2] with the first portion (to today's Route 159,[1] then called Route 5A[6]) opening in 1961.[2] It was extended to past Route 75 in 1966, with Route 57 being moved to the freeway around this time (the old alignment became Route 147).[1] In 1991, work to extend the freeway to Route 187 began, with the new section opening in 1995.[2] A further extension to Southwick has been proposed, but it was put on hold by then-Governor Mitt Romney in June 2005; nevertheless, Agawam's city council continues to urge the state to construct the extension.[2] The MA 57 freeway exits do not have numbers.
