Route 57 is an east–west Massachusetts state route that runs from Monterey to Agawam. The eastern 5.0 miles (8.1 km) in Agawam is a freeway that runs from Route 187 to the route's eastern terminus at U.S. Route 5.
The route begins in Monterey, at its intersection with routes 23 and 183. 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. In New Marlborough, Route 57 splits from Route 183 and follows a mainly easterly route with frequent curves, passing more farmland. During this stretch, there is a brief concurrency with Route 8 in Sandisfield to cross the Farmington River's west branch.
In Southwick, Route 57 starts to enter a more suburban area. There are more concurrencies during this stretch, first with U.S. Route 202 and Massachusetts Route 10 in Southwick, and then with Route 187 in Agawam.
