Bridge work at the Interstate 83 split with Route 581 will cause traffic delays over the next two weeks, according to PennDOT.

On Tuesday and Wednesday, then again Feb. 18 and 19, construction crews will set bridge beams for the new Lowther Street bridge that spans I-83 in Lemoyne, PennDOT said.

The old bridge was demolished, and traffic currently is using a temporary bridge to cross the interstate.

Between 9 p.m. and 6 a.m. Tuesday and Wednesday (Feb. 12 and 13), there will be a single-lane restriction, plus 15-minute traffic stoppages between 11 p.m. and 5 a.m. as workers lift and set the bridge beams, PennDOT said.

Drivers traveling I-83 and Route 581 in Lemoyne will encounter a single-lane restriction at 9 p.m. Feb. 18 and 19, followed by an overnight detour between 11 p.m. and 5 a.m. to finish setting the bridge beams.

The demolished bridge was built in 1952 and was a "major contributing factor" to daily traffic bottleneck issues at the I-83 split, according to PennDOT.

The $8 million project is expected to be complete by the end of May.
