Miami Marathon Traffic Advisory: What Drivers Need to Know on Sunday, January 25

Drivers in Miami and Miami Beach should expect significant traffic disruption on Sunday, January 25, 2026, as the 24th Annual Life Time Miami Marathon and Half Marathon brings thousands of runners onto streets across downtown Miami, Brickell, Biscayne Bay and Miami Beach. Officials say road closures will begin early in the morning and continue into the afternoon, making advance travel planning essential for anyone heading through the area.

Traffic restrictions are scheduled from 6:00 AM until 2:00 PM. While some roads will reopen as runners pass through, authorities warn that reopening times may change depending on race conditions and public safety requirements.

Anyone travelling to the airport, PortMiami, Miami Beach or downtown business districts should leave earlier than usual and follow directions from police officers and traffic control teams positioned along the race route.

Travel reminder: Officers from the City of Miami Police Department, Miami Beach Police Department and Miami-Dade Sheriff’s Office will manage intersections throughout the event. Drivers should expect temporary detours and intermittent delays.

Race route affects several major Miami roads

The marathon starts near downtown Miami before crossing into Miami Beach through the Venetian Causeway. From there, runners continue through several neighborhoods before returning toward Biscayne Boulevard for the finish.

Officials recommend using the Julia Tuttle Causeway if travelling between Miami and Miami Beach during the busiest part of the morning. Access to PortMiami will remain available through NE 5th Street.

Anyone planning local travel may also find it helpful to check other travel and traffic updates before leaving home, particularly if multiple events are taking place across South Florida.

Major road closures and expected reopening times

Traffic impacts will vary throughout the morning. Some roads will reopen gradually once runners have cleared each section of the course.

Road Direction Expected closure
Biscayne Boulevard (SE 3rd St to NE 2nd St) Northbound and southbound 6:00 AM – 10:00 AM
MacArthur Causeway Eastbound 5:00 AM – 8:10 AM
Venetian Causeway Westbound 6:20 AM – 10:00 AM
NE 15th Street Westbound 6:25 AM – 10:15 AM
Brickell Avenue Both directions 6:35 AM – 11:10 AM
Rickenbacker Causeway Both directions 6:40 AM – 11:50 AM
Miami Avenue Multiple sections 6:30 AM – 2:00 PM
Bayshore Drive Both directions 7:00 AM – 12:45 PM

What drivers should know before leaving home

Because the race moves through multiple neighborhoods, traffic conditions will change throughout the morning. Even after a road officially reopens, nearby intersections may remain busy as vehicles are redirected and pedestrians cross the route.

Residents in Brickell, Coconut Grove, downtown Miami and Miami Beach should expect the heaviest congestion during the morning hours. Public transport or adjusted departure times may help reduce delays.

Visitors heading to hotels, cruise terminals or weekend events should confirm the best route before travelling, especially if using navigation apps that may take a few minutes to reflect live road closures.

City officials say the annual marathon attracts thousands of participants and spectators while generating business for hotels, restaurants and local attractions. They are asking motorists to remain patient, obey temporary traffic controls and use alternate routes wherever possible until roads fully reopen later in the day.
