By Mallory Allen | August 2025 | Fox 11
Main Street from North Monroe Avenue to North Jackson Street will be temporarily closed later this week.
The closure is scheduled to be in effect from 7 a.m. Thursday to 12 p.m. Friday, but work operations are weather dependent and subject to change.
The detour will utilize N. Monroe Avenue, University Avenue and N. Webster Avenue. Access to residences and businesses will be maintained. Motorists should anticipate back-ups, use caution while driving through the work zone and are encouraged to find alternate routes.
According to Green Bay's public works department, the closure is due to an ongoing sewer project by NEW Water, the brand of the Green Bay Metropolitan Sewerage District. It will help ensure that "our community can continue to flush the toilet, wash their hands, and run their businesses whenever they want."
NEW Water owns and operates miles of underground pipes -- including a series of larger, deeper pipes called an interceptor system -- located throughout Northeast Wisconsin. In downtown Green Bay, portions of this system have been in operation for nearly 100 years "and are in need of improvements in order to revitalize critical, aging infrastructure to protect public health and the environment."
