Rolling roadblocks are scheduled to begin around midnight to hold up traffic on Interstate 83 North heading to Route 322 East through the Eisenhower Interchange near Harrisburg.
Drivers should also expect traffic stoppages on Eisenhower Boulevard and several ramps in the area as construction crews work on the bridge that carries Route 322 East into the Eisenhower Interchange, PennDOT spokesman Greg Penny said.
State police will start the rolling roadblock around midnight in the area of the 13th Street exit.
Several ramps to northbound I-83 and eastbound Route 322 will be blocked, including the ramps to northbound I-83 from 19th Street (Exit 44B) and Paxton Street (Exit 45) and the ramp from southbound Eisenhower Boulevard to eastbound Route 322.
Penny said the work is weather permitting, and the restrictions are necessary to keep traffic off the bridge while construction crews remove jacks installed last week to enable replacement of the bridge bearings.
Traffic on Eisenhower Boulevard will be stopped as a safety precaution so that no drivers are under the Route 322 bridge during the operation.
Penny said the rolling roadblock and traffic stoppages should not take longer than 15 minutes.
If more time is necessary, he said construction crews will conduct a second rolling roadblock and traffic stoppage to complete the job, again for no longer than 15 minutes.
