Construction Update: 5/27/2020

The Mirimichi Bridge Replacement Project has been completed. The bridge was reopened to traffic and the temporary detour has been deactivated. The Town would like to thank the many residents that were impacted by this closure for their continued patience during the construction. At this time, due to the COVID-19 pandemic, there will be no formal ceremony for the bridge opening. However, the Town will plan to commemorate this event at a later date once it is safe for the public to attend.
