PennDOT Reopens Eastbound Route 283 in Dauphin County
The Pennsylvania Department of Transportation reopened eastbound Route 283 in Lower Swatara Township, Dauphin County, at around 9:45 p.m. tonight. The closure was located about a half-mile east of the interchange with Interstate 283 and the Harrisburg East toll plaza for the Pennsylvania Turnpike. Eastbound Route 283 had been closed since 9 p.m. on Friday so that construction crews could address a sinkhole that was undermining the concrete pavement of both eastbound lanes. This portion of eastbound Route 283 carries a daily traffic volume of nearly 26,000 vehicles.
Construction crews from Kinsley Construction, Inc. of York, Pennsylvania – conducting the repair work for PennDOT last night cut and removed a portion of the concrete pavement and found a large void under the centerline of the eastbound roadway measuring roughly 8 feet in diameter and 5 feet deep.
The crews excavated the hole to a dimension of 36 feet long, 16 feet wide, and 6 feet deep. No throat to the sinkhole was found. The crews then filled the hole with seven loads of large rocks and 36 cubic yards of concrete.
They placed subgrade and subbase material over the area and this morning poured concrete for a new concrete pavement slab. PennDOT had to wait until the quick-set concrete cured and was strong enough to carry traffic before being in a position to reopen eastbound Route 283.
