Motorists are advised that rolling roadblocks starting around midnight tonight will hold up traffic on northbound Interstate 83 heading to eastbound U.S. Route 322 through the Eisenhower Interchange in Swatara Township, Dauphin County.
The traffic delays are necessary in order to keep traffic off of the bridge that carries U.S. Route 322 East through the Eisenhower Interchange while construction crews reset bridge bearings. Operations to install new bridge bearings have been ongoing and since there are four spans to the bridge, and each span needs to be dealt with separately.
To accomplish the rolling roadblock, the Pennsylvania State Police will start it at around midnight on I-83 North in the vicinity of Exit 44-B at 19th Street leading to the Eisenhower Interchange. In addition, several ramps accessing I-83 North and U.S. Route 322 East will be affected during this operation: Paxton Street to I-83 North will be blocked and southbound Eisenhower Boulevard to U.S. Route 322 East and I-283 North to I-83 South will be detoured.
The rolling roadblock on U.S. Route 322 should not take longer than 15 minutes. The ramp blockages and detours should not last more than 30 minutes. If more time is necessary to reset the new bridge bearings, the construction crews will later conduct a second rolling roadblock on I-83 North and traffic stoppage on Eisenhower Boulevard to complete the operation.
