Harrisburg, PA: In Just One Weekend, Bridge Superstructure Demolished & Restored

Posted by Infra on Tuesday, June 30th, 2015

Instead of impacting traffic for roughly a year and a half with traffic restrictions for a bridge superstructure replacement, PennDOT took an innovative approach to replacing a 60-year old structurally deficient bridge superstructure on busy Route 581 in the Harrisburg region.

On the weekend of June 5, two lanes of eastbound Route 581 over 10th Street in Lemoyne were closed. The new bridge superstructure had been pre-assembled a short distance away and segments were lifted into place by a crane capable of carrying 650 tons.
This video shows the demolition of the eastbound structure.
