Northampton Underpass

This page details the construction of the railroad underpass in Northampton, Massachusetts in 2016–2017.

The underpass connects the Mass Central Rail Trail — on the east side of the railroad tracks — with the Northampton Bike Trail Network on the west side of the tracks.

The site drawing below, which is from the so-called Public Filing Cabinet on the City of Northampton’s website, shows the plan for the underpass that was presented to the city’s Planning Board in early 2014.

Current issues

West side of the railroad underpass – looking south
Northampton, Mass. | February 2, 2021

The image above shows an unplowed section of the bike path between the west portal of the underpass and the sidewalk on the south side of the Walgreens property on King Street.

This section of the path is used year-round by people who walk from the east side of the tracks to and from retail shops (in particular the Stop & Shop Supermarket) on the west side of the tracks.

We reported this issues to the City of Northampton in early February 2021. Someone from the city wrote back a few days latter with the news that this section of the bike path is not maintained during the winter.
