Florida Department of Transportation—Nassau County State Road 200 Operational Improvements

Florida DOT increased safety and efficiency for drivers in Nassau County, one of the fastest-growing counties in the state, with its $41 million State Road 200 Operational Improvements project—a project that included a new diverging diamond interchange. By moving traffic to the opposite side of the road, the interchange eliminates left turns in front of oncoming traffic, greatly improving safety. The movement within the interchange also eliminates the number of traffic signal phases, improving efficiency at the intersection and reducing traffic queues. Motorists now only experience two clearance intervals to move through the interchange instead of six or more clearance intervals found in other interchange designs. Additionally, the interchange is prepared to handle the growth in the region with several new housing developments less than a mile from the project limits.
