SR 408 Widening (Contract 253C)

The Central Florida Expressway Authority (CFX) needed a firm to provide drainage design solutions for three ponds and permitting services for 2-miles of expressway widening from 6-lane to 8-lanes, including a mainline toll plaza with express lane, from Conway Road to Oxalis Avenue.

DRMP provided the design solutions and served as the point of contact for all construction related issues including distribution of shop drawings and requests for information.   Other major elements included signalization, signing and marking, drainage, permitting (environmental and FAA), fiber optics, two mainline toll plazas, three ramp toll plazas, braided ramps, soundwalls, aesthetic, two interchange modifications, surveying, right-of-way mapping and lighting.  Adjacent project coordination was also key, as this project was part of the $600 million widening and improvements to the existing SR 408 system. 

The three ponds give stormwater runoff a place to settle that is not on the limited access roadway. These ponds have the capacity to support the new 8-lane road during major rain events.
