Closures & Detours

A key goal of the PMH1 Project is to minimize traffic disruptions and maximize predictability during the construction period for commuters, goods movers, residents and the public. Construction activity may involve short-term adjustments that affect vehicle traffic patterns, cycling and pedestrian access and marine and shipping schedules. These closures, detours and other construction updates are posted to the website.

Please note:  implementation dates for upcoming detours may shift due to weather conditions. The PMH1 Project team is committed to implementing all detours in a safe and timely manner.
The Project website will be updated regularly as dates are confirmed. The best way to stay informed is to subscribe to Email Updates and check Closures and Detours for detailed information on the construction activity affecting vehicle, pedestrian and marine/shipping traffic.
