Description 

This bridge was under construction for many years as part of a project to widen the Spaulding Turnpike. The original 1966 bridge was apparently retained, but with several modifications to both the substructure and the superstructure to support a wider roadway. Additionally, a new parallel bridge built to be identical to the 1966 bridge was constructed in 2016 and erected in a way that it shares the foundations of the original bridge. As such, the fact that the crossing is today a twin-span is not immediately obvious.
