I-44 and I-55 Restrictions to Impact Midday Commute; Winter Storm Watch Begins Tonight

Friday Morning Traffic Overview

Commuters in St. Louis can expect a relatively clear start to their Friday morning on January 30, 2026, following the major snow clearing efforts from earlier this week. However, the midday and evening commutes will be significantly more challenging. MoDOT has resumed several high-impact pavement repair projects, and a new Winter Storm Watch has been issued for the region starting late tonight. While major arterials like I-64 and I-70 are currently flowing at normal speeds, several planned lane closures beginning at 9:00 a.m. will likely cause congestion through the afternoon.

Major Arterial Work and Lane Closures

Motorists should be prepared for significant bottlenecks on the following routes today:

• I-44 (St. Louis City): Two eastbound lanes will be closed between Hampton Avenue and Grand Boulevard from 9:00 a.m. to 6:00 p.m. for pavement repairs. This is expected to cause heavy delays for those heading into the city during the lunch hour and early afternoon.
• I-170 (St. Louis County): One northbound lane will be closed at the Page Avenue interchange from 9:00 a.m. to 3:00 p.m. for bridge maintenance.
• I-55 Corridor: Ongoing rehabilitation projects continue to restrict movement in South City. The Virginia Avenue on-ramp to southbound I-55 remains closed, as do the ramps at Loughborough and Germania. Additionally, one southbound lane is closed from I-44 to north of Bates.
• I-270 (Chain of Rocks Bridge): While lanes are open during the day, the Illinois Department of Transportation has announced that repairs between Illinois 3 and Riverview Drive will require lane closures starting at 9:00 p.m. tonight. Drivers should plan alternate routes if traveling late this evening.
• Route 21 (Green Park to Gravois): Single lane closures in both directions are scheduled from 6:00 a.m. to 2:00 p.m. for utility work.

Winter Weather and Cold Alerts

The City of St. Louis has extended the Code Blue Level 4 activation through Friday morning due to dangerously low temperatures. While road surfaces are currently dry and treated with brine, the National Weather Service has issued a Winter Storm Watch effective from late Friday night through Sunday morning. Forecasters are predicting between 4 to 6 inches of snow accumulation. Commuters are advised to complete their travel before 9:00 p.m. tonight, as conditions are expected to deteriorate rapidly overnight with falling temperatures and increasing wind chills.

Public Transit and Local Disruptions

Metro Transit is currently operating on a regular schedule, but riders should expect potential delays later this evening as the new weather system approaches. Additionally, residents should be aware of a scheduled national strike and potential protests downtown near federal buildings today, Jan. 30, which may lead to localized street blockages and increased pedestrian traffic. City officials recommend allowing an extra 20 minutes for any cross-town travel this afternoon.
