New Westbound I-270 Mississippi River Bridge Opening Delayed, Now Expected Next Weekend

Friday, November 13, 2026 · Society · GSM News

The Illinois Department of Transportation issued a traffic update on November 13: the new westbound I-270 Mississippi River Bridge will not open to traffic on November 16 as previously announced. Additional work on the bridge's expansion joints is needed before it can open, and the bridge is now expected to open next weekend.

The new span is part of the Chain of Rocks twin bridges crossing the Mississippi River between Madison County, Illinois, and Missouri, the centerpiece of a combined $531.6 million investment in a critical freight and travel corridor in the Metro East. The bridges are an achievement of Gov. JB Pritzker's Rebuild Illinois capital program, and transportation officials from both states had already cut the ribbon on the new bridge.

Drivers should continue using the existing crossing arrangement until the westbound span opens and watch for further updates.
