Population growth drove the need for a new interchange at I-95/Viera Boulevard in Brevard County to improve driver safety and efficiency while increasing capacity for the current congestion and projected traffic demand. The solution was new interchange, a Diverging Diamond Interchange (DDI), which was the first of its kind in the Florida Department of Transportation’s District 5.
The new DDI configuration includes mast-arm signalized intersections at two ramp terminals on Viera Boulevard. The new ramp intersections moved the pedestrian sidewalks from the outside of the bridges to the inside, requiring the installation of pedestrian fences and the construction of a barrier to separate the sidewalk from the travel lanes, while introducing Rectangular Rapid Flashing Beacons (RRFBs) at on-ramps.
Signing and pavement markings safely direct traffic through the crossover and lighting cutoffs reduce glare into adjacent residential areas. Signal timings were developed for the DDI and SYNCHRO was run for the arterial timings along Viera Boulevard including the new interchange.
