The Summit Bridge, one of six bridges maintained and operated by the U.S. Army Corps of Engineers Philadelphia District, is undergoing steel repairs and painting to protect against corrosion.

In October 2011 the contractor, Marinis Brothers Inc., started sand blasting the south side of the bridge and began to install gusset plate stiffeners to reinforce the bridge beams and trusses. The repairs began in April, will cost approximately $10 million and take about another year to finish. There will be periodic lane closures that will be coordinated with the Delaware Department of Transportation.
