Zilwaulkee Bridge

Location: Zilwaukee Bridge – I-75/ US-23 over the Zilwaukee River


In 2013, the mile and a half long Zilwaukee Bridge was shut down for sealer overlay (healer sealer), structural crack repair to bearing pads, and bearing pad replacement.

Smith’s Waterproofing installed sealer overlay (healer sealer) over the entire North and South Bound decks, totaling 1,170,000 square feet.  Smith’s also performed epoxy crack injection on the bearing pads, which are designed to support up to 8 million pounds each.

To complete the work on schedule, Smith’s utilized three shotblasters and one installation crew for the healer sealer. Two additional crews were utilized for the structural crack injection of the bearing pads.

Due to the height of the bridge, which reaches 120’ at its highest point, boom trucks and snooper trucks were utilized to reach many of the bearing points to perform crack injection. Smith’s performed epoxy crack injection on a total of 32 bearing points.

Smith’s Waterproofing had limited time frame to complete this project, and performed work in just 15 days during September and October in 2013, and another 15 days in September and October of 2014. This project was completed with no reportable injuries, finished on time, and under budget.
