Description 

"This stone arch is dated to 1847 by the Andover Historical Society Newsletter. It is constructed of coursed ashlar blocks and has concave abutments. It carries one track although it was constructed to carry two. A concrete cap that rests on the top of the bridge must have been added when the grade level was raised. This bridge is located within the Shawsheen Valley Multiple Resource Area and retains its natural setting." -P.K. Lazrus, MBTA Historical Property Survey Phase II, 11/1987

=====

In 2013, this bridge and its northern twin were reconstructed with a deck girder span being installed above the arch to act as the load-bearing mechanism. The arches were preserved below, but are not load-bearing.

MBTA - Shawsheen River Bridge
Posted February 27, 2016, by John C (jcitron [at] krpartners [dot] com)

Status is active as this is the mainline from Boston to Portland and serves the MBTA Commuter Rail Haverhill line and Amtrak's Downeaster along with Pan AM Railways for freight between Portland and points west.

This line is being re-double-tracked after having been reduced to single track in the mid-1970s when the MBTA first took over the commuter rail service. With the increase in traffic, the second track is being added back in between Wilmington Jct. and Frye (Shawsheen Village).
