Interstate 83 in eastern Cumberland County will be closed for several hours Monday night as construction crews set bridge beams for the new Lowther Street bridge in Lemoyne.
Weather permitting, the road will be restricted to a single lane from 9 p.m. to 11 p.m. From 11 p.m. Monday to 5 a.m. Tuesday traffic will be detoured off the bridge as the remaining beams are set into place over Interstate 81.
The original concrete bridge that carried Lowther Street over I-83 was built in 1952 and is now considered functionally obsolete. Traffic on Lowther Street is currently using a temporary structure to cross over I-83 while the new bridge is built.
The work is part of a nearly $8 million contract to install a temporary bridge, remove the original Lowther Street bridge and construct a new two-span bridge large enough to accommodate four lanes of mainline I-83 as well as three ramps underneath. The old bridge was a major contributing factor to the bottleneck on I-83 North approaching the City of Harrisburg and Route 581 West.
On Monday evening and early Tuesday morning, Traffic from I-83 North will be directed off at Brandt Avenue, turn right onto Lowther Street through Lemoyne and then allowed to get back to I-83 North. I-83 North traffic headed to Route 581 West will follow Brandt Avenue to Lowther Street and continue on I-83 North across the Susquehanna River into Harrisburg and then be directed off at Exit 44A for 13th Street to return to I-83 South and cross back over the Susquehanna River and enter 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 41B for Highland Park, turn right onto Lowther Street through Lemoyne over the interstate and turn left at 10th Street to I-83 South.
