Winter Recovery and Bridge Projects: Sunday Traffic Outlook for St. Louis

Current Road Conditions and Winter Recovery

As of Sunday morning, February 22, 2026, the City of St. Louis remains under a state of emergency originally declared by Mayor Cara Spencer. While the major winter storm has passed, the emergency declaration is active through today to facilitate ongoing snow removal and emergency procurement. Most major arterials have been cleared, but commuters should remain cautious on secondary roads and overpasses where residual ice and snow piles may persist. Metro Transit has resumed normal operations across most of the network, though officials recommend checking for specific bus routes that may still be operating on designated snow routes as cleanup continues.

Major Highway Construction and Closures

Several long-term infrastructure projects continue to impact traffic flow across the metro area this Sunday. Drivers should plan for the following disruptions:

• I-55 Bridge Rehabilitation: In St. Louis City, significant work continues on the bridges over Loughborough Avenue and Weber Road. The ramps from Germania to northbound I-55 and from southbound I-55 to Germania remain closed through early 2026. Expect lane shifts and reduced speeds in these zones.
• I-55 Jefferson County Expansion: Further south, the $246 million corridor improvement project between Pevely and Festus is active. While weekend lane closures are minimized, drivers will encounter shifted traffic patterns as crews work to expand the interstate to three lanes in each direction.
• I-270 Chain of Rocks Bridge: Construction on the new bridge over the Mississippi River is in its final stages, with a target completion date late this year. Expect narrow lanes and a 55 MPH speed limit near the Riverview Drive interchange. The westbound exit and on-ramps at Riverview Drive remain closed as part of the interchange reconstruction.
• I-70 St. Charles County: Work continues on the widening project between Warrenton and Wentzville. Particular attention is needed near the I-70/I-64/U.S. 61 interchange, where bridge work may cause periodic overnight lane restrictions that bleed into early Sunday morning.

Public Transportation and Commuter Advice

MetroLink is operating on its standard Sunday schedule. However, riders should be aware of ongoing station improvements related to the Secure Platform Plan; while no full station closures are reported for today, temporary entrance modifications may be in place. For those using the MetroBus system, allow for an additional 10 to 15 minutes of travel time if your route passes through active construction zones in North County or South St. Louis City. Always check the official transit app for real-time adjustments before heading to your stop.
