Old Greenwich sewer main replacement project enters final phase, may disrupt traffic

As the final phase of work in the Old Greenwich sewer force main replacement project begins, it is expected to have a major impact on traffic for the next several weeks. Temporary road closures and detours are possible as the work progresses, the Department of Public Works said. Work is scheduled in Work Zone 6, which is the traffic circle where Arch Street, West End Avenue and Summit Road meet in Old Greenwich, and Work Zone 1, which is on Oval Avenue near the Riverside train station. Construction on the sewer main replacement has been underway since August 2021, when it began in Work Zone 1 near the Riverside Train Station. It has proceeded through the six work zones in Riverside and Old Greenwich over the past year. Although the construction is expected to be completed by the end of October, finishing touches on the full project will continue until 2023.
