June 8 Marks Start of Full Road Closure on North Street for Bridge Project

The North Street Bridge over West Brothers Brook in Greenwich is undergoing a $4.52 million replacement project that includes a full road closure from June 8 through August 28, 2026. Estimated Completion is spring 2027.

The last day of school for Greenwich Public Schools in 2026 is Monday, June 22 for the majority of students. For grades 6 and 9, the last day of school is Friday, June 19

The bridge is over West Brothers Brook, between Cotswood Road and Macpherson Drive.

In the lead up to the full road closure, work continues with alternating one-way traffic as crews perform micropile drilling and installation, which DPW said is an important step in strengthening the bridge structure.

Initially, DPW wanted to avoid closing the road completely. Back in 2024 the project was estimated to involve one-way traffic at times over a period of 18 to 24 months. Neighbors warned of a “catastrophe,” given traffic already often backs up on North Street near the bridge and there are 8 schools and 7,000 students within one mile of the “choke point” at Parsonage Rd and North Street.

During the full road closure, residents are urged to plan ahead and allow extra travel time.

The bridge was originally built in 1909 and rebuilt in 1950. After the last inspection on March 7, 2022, the bridge was deemed in critical condition. This resulted in emergency repairs.
