Division Street Bridge

HNTB provided design services for the complete reconstruction of 5,155 feet of Division Street and 534 feet of Elston Avenue, which involved the removal and replacement of two bridges.

The new Division Street Bridge over the North Branch of the Chicago River is a 242-foot-long tied-arch structure, specially designed for the arch ties to not be fracture critical members through post-tensioned concrete tie elements. The concrete deck is also longitudinally post-tensioned to reduce the likelihood of cracking.

Since the bridge replaces a bascule bridge, the HNTB design allows the arch span to lift vertically, providing the 40-foot navigation clearance required by the U.S. Coast Guard for cases of emergency.

• Tied-arch span over the North Branch of the Chicago River
• Project helps to improve vehicular movement along the busy Division Street corridor
• New bridge improves important downtown access while also providing necessary navigation clearance
