South Florida Roads (Miami-Dade and Monroe Counties)


The Florida Department of Transportation (FDOT) has begun a roadway safety improvement project along SR A1A/MacArthur Causeway when approaching SR 907/Alton Road in the City of Miami Beach.


A flashing beacon will be installed along eastbound MacArthur Causeway when approaching Alton Road. Once the project is complete, the flashing beacon activates and alerts drivers when the traffic signal located at Alton Road is red for eastbound MacArthur Causeway traffic.


During the weeks of June 3 and June 10, 2019, a partial lane closure of the eastbound MacArthur Causeway right turn lane onto southbound Alton Road will occur for installation of conduit and flashing beacon at Alton Road can occur from. 
  • 9 a.m. to 3:30 p.m. — Monday through Friday

The right turn from eastbound MacArthur Cswy onto southbound Alton Road will still be accessible for drivers. This work will be scheduled to avoid working at the same time as the upcoming MacArthur Causeway flyover closure.
