WILLIAMSTOWN, Mass. -- The long-awaited reconstruction of South Street will begin on Monday, creating a long-term traffic detour that will begin on Tuesday, the town said last week.

 

Starting Tuesday, April 15, South Street will be one way, southbound from Field Park to the Clark Art Institute.

 

For the duration fo the 2025 construction season, all traffic leaving the Clark will be directed to Gale Road to Water Street (Route 43).

 

The first week of construction will largely involve fencing trees for their protection and the installation of sedimentation and erosion controls.

 

Ultimately, the project will replace all underground infrastructure in the South Street Corridor and reconstruct the traveled way.

 

"Upon completion in the summer of 2026 the newly renovated South Street will be built to Complete Streets standards with sidewalks along the eastern side of the roadway, narrowed travel lanes to reduce traffic speed, full bike lanes, and two new mid block pedestrian crossings," town officials said in announcing the road work.
