The 430-foot crossing was built to replace Chicago’s historic, but aging North Avenue Bridge. The new bridge features an unusual hybrid cable-stay/suspension design.
BendTec fabricated the bridge’s four sets of steel anchor pylons, each 45 feet tall and weighing 95,000 lbs. the pylons rest on 10 smaller micropiles, extending into the bedrock. From the pylons, 24 cable-stays support the approach spans and the ends of the center span. A suspension cable supports the center of the main span.
