On Monday morning, traffic using the existing DuBoistown River Bridge will be detoured to the Maynard Street Bridge.
The detour is the next major phase of construction for the DuBoistown Bridge connecting DuBoistown and Williamsport over the West Branch of the Susquehanna River.
The detour will allow construction to begin on the south approach of the new bridge and the deck replacement for the nearby Brook Street Bridge over Mosquito Creek.
The detour is scheduled to be in effect until mid-August.
During this phase of construction, access to Susquehanna State Park and the Hiawatha paddle wheeler will be only from the north via Arch Street.
Once the south approach is completed in mid-August, the new bridge will only be used to access Susquehanna State Park and the Hiawatha from the DuBoistown side of the river.
Also in mid-August, Arch Street will be closed on the north side of the river from the state park entrance to the entrance to the sewage treatment plant for roadway reconstruction at the north approach of the bridge.
The new DuBoistown Bridge is expected to be opened to unrestricted traffic by mid-November. The replacement project will cost $18 million.
