Work to realign the shuttered northbound span of the I-495 bridge over the Christina River in Wilmington started Wednesday morning, state transportation officials said.
Crews are using the same process used to repair the southbound lanes but the northbound side has a more pronounced tilt, Delaware Department of Transportation spokesman Layton Gregory said in a news release.
That tilt, Gregory said, is causing more stress on the structure and it will take longer for crews to correct the lean than it did on the southbound side.
Once the northbound bridge deck is realigned, he said steel bracing will be welded into place and support towers will be anchored to the ground with steel cables.
DelDOT still expects to have the northbound bridge reopened by Labor Day.
The Interstate bypass was closed in both directions approaching the bridge on June 2nd after support columns were found to be tilting. The southbound side reopened on July 31.
Prior to the closure, about 90,000 vehicles traveled over the bridge each day.
