This project involves reconstructing the Butler Boulevard/San Pablo Road interchange as a diverging diamond interchange (DDI). Through its unique design, a diverging diamond interchange enhances mobility and improves safety by eliminating conflict points for motorists seeking to turn left. In a DDI, drivers cross over to travel briefly on the left side of the road and then seamlessly return to the right side of the road on the other side of the intersection. Additionally, the DDI promotes efficiency with only two clearance intervals (the time for traffic signals to change from green to yellow to red) instead of the six or more found in other interchange designs. FDOT District Two is currently constructing diverging diamond interchanges at I-95 and State Road A1A (State Road 200) in Nassau County, First Coast Expressway and Henley Road in Clay County and First Coast Expressway and State Road 16 in Clay County. A video with more information about diverging diamond interchanges is available at www.nflroads.com/DDI.
During construction, driver speeds will be restricted to 30 miles per hour on San Pablo Road and 35 miles per hour on ramps to and from Butler Boulevard. No lane closures will be permitted from 6 a.m. to 8 p.m. daily. Lane closures for the upcoming week are posted every Friday afternoon at http://www.nflroads.com/trafficreport.
