Benesch prepared the roadway and drainage plans for 1.37 miles of SR 600 6-laning from Portage Street to Vine Street (US 192) in the City of Kissimmee, Florida.
The existing 4-lane urban roadway was widened toward the median for the
6-lane improvements. The majority of the project did not require R/W to construct these improvements, with the exception of the Vine Street intersection. That intersection required a dual left turn lane, which required widening and additional R/W. The 50-year old drainage system was analyzed and we determed a majority of it could be salvaged.
Benesch also proposed construction of additional piping in the median area to minimize impacts to the existing roadway and R/W, while still providing the drainage needs. Several outfall systems were also analyzed for capacity, including the expansion of two existing stormwater facilities for treatment and attenuation. The ultimate outfall was to the West City Canal, a regulated floodway. Analysis was required on this canal to assure the permitting agencies that there was no change in the floodwaters (No-Rise).
The project also included roadway plans, drainage plans, signing and marking, signalization, traffic control and permitting.
