HARRISBURG, Pa.– The bridge that carries Newberry Road over Route 283 in Londonderry Township, Dauphin County, will be closed to all traffic starting Monday, October 24, for a construction project to repair damage to the bridge.
The bridge carries approximately 700 vehicles on a daily basis. A signed detour will direct motorists around the bridge closure by way of Schoolhouse Road, Creek Road, and Swatara Creek Road.
It should take about a month for the contractor to remove the damaged beam on the bridge and replace it with a new beam, repair the concrete bridge deck, and replace the parapet. On the nights when the damaged beam is removed and when the new beam is installed, motorists on eastbound Route 283 should expect to encounter short-term traffic stoppages or rolling road blocks while these operations are underway, which will occur between 10 PM and 5 AM.
This is the second of two similarly damaged bridges to be repaired. The first started on September 26 when the Union Street bridge over Route 283 in Lower Swatara Township was closed for repairs. There is about two weeks left for curing of the new concrete on the Union Street bridge deck before the bridge can be reopened to traffic.
Both bridges were damaged on May 1 last spring when the boom of an excavator carried on a trailer hauled by a truck on eastbound Route 283 struck them.
The under-clearance for the Union Street bridge is 14 feet 10 inches; for the Newberry Road bridge, the under-clearance is 14 feet 5 inches. Any load higher than 13 feet 6 inches requires a hauling permit from PennDOT. Both Union Street and Newberry Road are local township roads, but the bridges over Route 283 are owned and maintained by PennDOT.
PennDOT has contracted with Clearwater Construction, Inc. of Mercer, Pennsylvania to replace the fascia beams of both bridges and conduct deck and parapet repairs at a cost of $407,050. The repairs to both bridges should be finished by early December.
