Throughout the month, three detours will affect roads in Lycoming County - Arch Street in Williamsport, Route 220 in Piatt Township near Jersey Shore and Silver Bridge over Pine Creek near Jersey Shore.
Susquehanna Supply Co. began switching traffic on Wednesday to the next phase of construction for the new DuBoistown Bridge, which will affect those going to Susquehanna State Park and the Hiawatha paddle boat, said Rick Mason, state Department of Transportation spokesman.
People driving toward the park from Interstate 180 will cross Maynard Street Bridge, turn right onto Riverside Drive, turn right onto the bridge and turn left into the park, Mason said.
The DuBoistown Bridge, left, nears completion with the old bridge next to it. The barge on the right side of the bridges was used to bury the new sewer line under the river bed from DuBoistown to Williamsport. The line connects a new overflow tank in DuBoistown to the waste water treatment plant on the Williamsport side.
Work progresses on a new DuBoistown Bridge, parallel to the old bridge, as shown from the window of a helicopter.
Those who access the park from West Fourth Street also will have to use the detour because the Arch Street approach will be closed until mid-November, when traffic will return to the normal pattern for winter.
Mason said delays will be minimal as he does not expect much traffic to use the detour.
The new bridge will be available for traffic later in November, Mason said.
The construction is part of an $18 million bridge replacement project.
"One of the distinctions of the old DuBoistown Bridge is it's the last structurally deficient river crossing in northcentral Pennsylvania in our district," Mason said.
The funding for the project came from the federal money to replace structurally deficient bridges not yet programmed for replacement, following the Interstate 35 bridge collapse in 2007, Mason said.
In Jersey Shore, the historic Silver Bridge over Pine Creek will be closed briefly next Wednesday for a routine inspection from the PennDOT bridge inspection crew.
The crews will use a bridge inspection crane, so the bridge will be closed to traffic from 10 a.m. to noon.
Motorists may follow the detour that was in place during the bridge's recent rehabilitation, which is Tiadaghton Avenue, Railroad Street, Allegheny Street, Main Street and River Road, Mason said.
Also in Jersey Shore, a PennDOT maintenance crew will perform base repairs on Route 220 on Sept. 26 for routine maintenance. If a second day is needed, work will continue Sept. 27.
The work will take place in both the north- and southbound lanes from just west of the railroad overpass to the Route 287 interchange.
The northbound Route 220 turning lane to Route 287 north will close at 7 a.m. and reopen at 3 p.m., barring any unforeseen issues.
During the turning-lane closure, drivers going north on Route 220 who want to go north on Route 287 will be directed to the West Fourth Street exit in Williamsport, then to Route 220 southbound to access Route 287.
