Downtown Binghamton Pedestrian Tunnel to Close for Major Makeover

A dark and dirty tunnel in Binghamton is about to get a big facelift as part of a $47 million infrastructure project.

Rehabilitation work is planned for the Carroll Street pedestrian tunnel over the next three months.

According to the state Department of Transportation, the walkway will be shut down starting Monday morning to allow crews to make a series of improvements.

The tunnel's makeover is part of the 363 Gateway Project that has been in the works for more than a decade. The initial phases of construction for the project began this summer.

The Carroll Street walkway starts at the southeast corner of the Woodburn Court II apartment complex.

A DOT news release notes the tunnel provides access between both sides of Route 363 as well as to a kayak and boat portage area along the Susquehanna River near the Rockbottom Dam.

The upcoming rehabilitation work will include replacement of the tunnel's ceramic tile, installation of new lighting and improvements to its entrances.

The work will occur during daytime hours. Pedestrians should follow a posted detour.

Eventually, the Carroll Street ramp to Route 363 will be permanently closed but the pedestrian tunnel will remain open.

A half-mile-long pedestrian pathway will be built along the Susquehanna River running from the Rockbottom Dam to Confluence Park.
