PennDOT to replace Route 581 bridge in Lemoyne this month as part of $22.1 million contract

Over the next two weekends, contractors will be replacing the Route 581 bridge in Lemoyne with a slightly higher span, state Department of Transportation officials said.

Weekend work is planned to avoid disrupting the more than 86,000 vehicles that cross the bridge daily, PennDOT said in a news release. To avoid delays, travelers should plan ahead and seek an alternate route.

Otherwise, eastbound traffic will be detoured from 9 p.m. Friday to 6 a.m. Monday. Westbound traffic will be restricted to one lane.

The bridge carries Route 581 traffic over 10th Street in Lemoyne. The new bridge will be slightly higher, which will assist trucks that use 10th Street, the release said. 

The bridge replacement is part of a $22.1 million contract awarded in July 2013 to J.D. Eckman Inc., of Chester County.

The contract includes several “safety and congestion mitigation improvements” to the I-83, Route 581 interchange and adjacent ramps, the release said.

Sections of the new bridge have been pre-fabricated a short distance away. They will be transported to 10th Street and lifted into place by a crane capable of carrying 650 tons, the release said.

This construction technique will significantly reduce the duration of traffic impacts on Route 581, officials said.

Next weekend, Route 581 westbound lanes will be closed at I-83. Northbound I-83 motorists headed to Route 581 will continue on I-83 through Harrisburg to I-81 South, to Route 581 East.

Southbound I-83 motorists headed to Route 581 West will use Exit 40-B to Carlisle Road, to 18th Street, to Hummel Avenue, to State Road, to Gettysburg Road, to Simpson Ferry Road, to Lower Allen Drive, to U.S. 15 North, to Route 581 West.

Eastbound Route 581 motorists will also encounter a left-lane restriction and intermittent traffic stoppages as sections of the existing bridge are removed and the new bridge deck is set into place, the release said.

Following the placement of the new bridge, the contractor is scheduled to resurface both eastbound and westbound bridge decks with a latex-modified concrete overlay on subsequent weekends. This work will also require weekend detours, one direction at a time.

The project is scheduled to finish this summer.

Built in 1958, the current bridge is a three-span continuous steel girder bridge. The new structure will be the same dimensions, but by using shallower steel girders, the clearance on 10th Street beneath the bridge will rise from 13 feet, 11 inches to 14 feet, 7.5 inches.
