Overnight Closures on Dolphin Expressway and Metrorail Service Shifts Today

Miami Traffic and Commute Update: Wednesday, March 4, 2026

Commuters in Miami should prepare for a mix of ongoing construction impacts and specific service adjustments on public transit for today, Wednesday, March 4. While major arteries are moving steadily this morning, several significant overnight closures and rail service changes are scheduled to affect your evening and late-night travel.

Major Roadworks and Expressway Closures

The I-395/SR 836/I-95 Design-Build Project continues to be the primary driver of traffic shifts in the downtown area. Key alerts for today include:

• SR 836 (Dolphin Expressway): Expect a full closure of all eastbound lanes at NW 17th Avenue starting at 10 p.m. tonight. This closure is scheduled to last until 5:30 a.m. Thursday. Drivers are advised to use NW 12th Avenue as a detour point to reconnect with I-95 or the MacArthur Causeway.
• SR 836 Lane Reductions: In addition to the full closure, two lanes will be closed as needed in both directions between I-95 and NW 17th Avenue from 9 p.m. to 5:30 a.m. for ongoing bridge work.
• I-95 Express Lanes: Maintenance work near the Broward/Miami-Dade line may trigger contingency closures tonight. If active, southbound express lane traffic will be diverted at Sunrise Boulevard.

Public Transport and Transit Alerts

Miami-Dade Transit has issued several alerts for those relying on the Metrorail and Metromover systems today:

• Metromover Service Modification: The Miami Avenue Station remains closed until further notice due to technical maintenance. The Inner Loop service is currently operating on a modified schedule, running on the same track and in the same direction as the Omni and Brickell loops. Passengers heading to Miami Avenue should use the Third Street Station as the nearest alternative.
• Metrorail Single-Tracking: After 9 p.m. tonight, single-tracking will be in effect between the Vizcaya and Dr. Martin Luther King, Jr. stations. Both Green and Orange Line trains will operate every 30 minutes during this window.
• Dadeland South Station: Ongoing canopy construction for the new Intermodal Station project means trains are serving only one side of the platform. Commuters should allow for an extra 10 to 15 minutes of travel time when arriving or departing from the southern terminus.

Commuter Recommendations

For those traveling late tonight, it is highly recommended to use navigation apps to monitor real-time detours around the Dolphin Expressway. Metrorail riders should check the GO Miami-Dade Transit app for the latest arrival times, particularly during the late-evening single-tracking period.
