Overview for Saturday, January 31, 2026

Jacksonville commuters should prepare for a busy Saturday as several major events and long-term infrastructure projects converge. Residents are advised to account for significant congestion at the Beaches due to the DONNA Marathon Weekend and ongoing detours related to the widening of I-10 and the Northside interchange improvements. Additionally, a cold weather alert is in effect, with local authorities providing specialized transport for those seeking shelter.

Beaches Congestion: DONNA Marathon Weekend

The 19th annual DONNA Marathon Weekend is in full swing, with all race events concentrated at the Beaches this year. Drivers should expect heavy traffic and intermittent road closures in the following areas:

• DONNA 110 Ultra Marathon: Athletes began their 110-mile journey early this morning at 7:30 a.m. Cheering sections are expected near the Hampton Inn Oceanfront in Jacksonville Beach.
• FIS DONNA 5K and Family Fun Run: These events are concentrated at the Beaches starting between 8:00 a.m. and 9:30 a.m.
• Health & Wellness Expo: Located at the Hilton Jacksonville at Mayo Clinic (Transformation Way), the expo will draw significant traffic to the Mayo Clinic campus through 4:00 p.m. Free parking is restricted to designated lots.

Major Highway Roadworks and Detours

The Florida Department of Transportation (FDOT) continues work on two massive multi-year projects that will impact regional travel today:

• I-10 Widening: Construction between I-295 and I-95 remains active. Commuters on the Westside should watch for closures on the I-10 West off-ramp to U.S. 17 (Roosevelt Boulevard). Detours are currently routing traffic to McDuff Avenue.
• I-95/I-295 North Interchange: This $176.8 million modernization project is nearing its final phases. While northbound I-95 now features six lanes through the interchange, be alert for temporary lane shifts and specialized ramp configurations near Airport Road.

Public Transit and JTA Alerts

The Jacksonville Transportation Authority (JTA) implemented new service enhancements on January 26. Riders should check their updated schedules for Routes 8, 10, 18, and 28. Specific alerts for today include:

• Route 11: A detour will begin at 7:00 p.m. tonight to accommodate the Jacksonville Iceman game at the VyStar Veterans Memorial Arena. Several stops along A.P. Randolph Blvd and Union Street will be bypassed.
• Route 19: Due to a sinkhole at Fort Caroline Road and Townsend Blvd, a long-term detour remains in place.
• Cold Weather Support: JTA is coordinating with the city to provide free transportation to the Legends Center on Soutel Drive for those requiring overnight shelter during this weekend's record-low temperatures.

Downtown and Local Events

In addition to hockey downtown, the Prime Osborn Convention Center is hosting the Villain Arts Tattoo Festival, which may slow traffic on Water Street. Commuters heading toward the University of North Florida should expect minor delays near the Adam Herbert University Center for the Active After 50 Expo starting at 10:00 a.m.
