Work on the new Lowther Street bridge over Interstate 83 in Lemoyne will cause northbound lane restrictions and traffic stoppages next week.
PennDOT spokesman Mike Crochunis said drivers should expect single-lane restrictions between 9 p.m. Tuesday and 6 a.m. Wednesday, and 15-minute traffic stoppages between 11 p.m. and 5 a.m., while the bridge beams are lifted and set in place.
Lowther Street traffic is currently using a temporary structure to cross over I-83 while a new bridge is built.
The work is part of a nearly $8 million project to build a new two-span bridge large enough to accommodate four lanes of I-83, as well as three ramps underneath, in order to eliminate the bottleneck on I-83 North approaching Harrisburg and Route 581 West.
During the remainder of the project, I-83 traffic will be detoured twice to set the new bridge beams and to remove the temporary structure. The next detour is scheduled during the overnight of February 18-19.
Crochunis said drivers on I-83 and Route 581 in Lemoyne should expect a single-lane restriction in each direction at 9 p.m. February 18, followed by an overnight detour between 11 p.m. and 5 a.m.
I-83 North will be directed off at Brandt Avenue, turn right onto Lowther Street through Lemoyne back to I-83 North. I-83 North traffic headed to Route 581 West will also follow Brandt Avenue to Lowther Street and continue on I-83 North across the Susquehanna River into Harrisburg and be directed off at Exit 44-A for 13th Street to I-83 South back across the Susquehanna River to Route 581 West.
I-83 South will be directed off at Exit 42 for Lemoyne follow Lowther Street over the interstate, turn left at 10th Street and back to I-83 South.
Route 581 East traffic headed to I-83 South will be directed to I-83 North to Exit 41-B for Highland Park, turn right onto Lowther Street through Lemoyne over the interstate and turn left at 10th Street to I-83 South.
PennDOT expects work on the new Lowther Street bridge to be completed by the end of May.
