Rolling roadblocks scheduled to start around midnight tonight will hold up traffic on northbound Interstate 83 heading to Route 322 East through the Eisenhower Interchange in Swatara Township, Dauphin County.
PennDOT spokesman Greg Penny said the traffic delays are necessary in order to keep traffic off of the bridge that carries eastbound Route 322 into the Eisenhower Interchange.
Penny said construction crews will jack up the bridge deck and replace the bearings on which the deck sits.
State police will start the rolling roadblock at around midnight on northbound Interstate 83 near the 13th Street exit.
Several ramps to I-83 North and Route 322 East will be blocked during the operation, including the on-ramps to I-83 North from 19th Street and Paxton Street, as well as the on-ramp from southbound Eisenhower Boulevard to Route 322 East, Penny said.
Traffic on Eisenhower Boulevard will be stopped as a safety precaution so that no drivers are under the Route 322 bridge while the operation is underway.
Penny said the rolling roadblock and traffic stoppages should not take longer than 15 minutes. If more time is necessary, the construction crews will later conduct a second rolling roadblock on Route 322 and traffic stoppage on Eisenhower Boulevard to complete the operation - again, for no longer than 15 minutes.
