The northbound I-95 ramp to State Road (S.R.) 200, exit 373, will be detoured Monday night, June 24 from midnight to 5 a.m., weather and schedule permitting. The detour is necessary for crews to install an overhead sign structure. Once the structure is installed the ramp will reopen. Drivers will be detoured north on I-95 to U.S. 17, exit 380, and travel south to reconnect with State Road 200. A map of the detour is attached for convenience.
The S.R. 200 improvement project in Yulee consists of the reconstruction and widening of 2.2 miles of S.R. 200/A1A from west of I-95 to west of Still Quarters Road, widening of ramps at Interstate 95/A1A exit 373 (to Yulee/Callahan/Amelia Island/Fernandina Beach), and the reconfiguration of the interchange under I-95 into a diverging diamond interchange (DDI).
The widening project will increase the roadway from four lanes to six lanes and includes raised medians, bicycle lanes, curb and gutter, sidewalks and high mast lighting.
J.B. Coxwell Contracting, Inc. of Jacksonville is constructing the $40 million project. The project is expected to be completed in summer 2020, weather and unforeseen circumstances permitting.
A diverging diamond interchange (DDI) is a type of interchange where the two directions of traffic below I-95 briefly drive on the opposite side of the road. The configuration will promote safety, due to the elimination of dedicated left turn traffic signal cycles. Additionally, the DDI configuration 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.
