Do you support long-term highway construction even when it causes overnight closures?
The Florida Department of Transportation will close sections of State Road 836 overnight on November 7-8, 2026, as crews continue double-decking the Dolphin Expressway. Eastbound lanes close at Northwest 17th Avenue from 11 p.m. to 8 a.m., and all lanes between Northwest 12th and 17th avenues close by 1 a.m.
Why it matters
The overnight closures affect drivers traveling through the Dolphin Expressway corridor in Miami while crews add a new road level above the existing section. The project connects to Interstate 395 and the MacArthur Causeway once complete.
The overnight closure window runs from 11 p.m. to 8 a.m. for eastbound lanes, with all lanes between Northwest 12th and 17th avenues closed by 1 a.m. The total project cost is $866 million, with completion not expected until late 2029.
The players
Florida Department of Transportation
The state agency responsible for maintaining and building Florida's highway network, including the Dolphin Expressway project.
The details
Crews are adding an additional road above the existing Dolphin Expressway section that connects to Interstate 395 and the MacArthur Causeway. Eastbound drivers can detour by exiting at Northwest 17th Avenue, turning right at South Miami Avenue, then turning right to access the I-95 ramps.
Timeline
November 7, 2026, 11 p.m.: Eastbound lanes close at Northwest 17th Avenue and westbound closures begin.
November 8, 2026, 1 a.m.: All lanes between Northwest 12th and 17th avenues are closed.
November 8, 2026, 8 a.m.: Closed lanes reopen.
Late 2029: Expected completion of the $866 million project.
Home Renovation Context
Long-running renovation projects like the Dolphin Expressway double-decking show how major infrastructure work in Miami can stretch for years with recurring overnight closures. Residents planning home projects near the corridor should expect the same kind of disruption through 2029.
Drivers using the Dolphin Expressway should plan detours through Northwest 17th Avenue and South Miami Avenue during the overnight closure windows. Commuters crossing the corridor after 11 p.m. or before 8 a.m. should allow extra travel time through 2029.
The takeaway
Drivers who regularly use the Dolphin Expressway should check closure schedules before late-night trips through the end of the project. Adjusting routes now can prevent delays during the 2029 build period.
What happens next
Eastbound closures are scheduled to resume on future nights until the project is finished in late 2029.
