Another comprehensive and highly involved project requiring a wide range of WGI’s services, responsibilities included roadway design; drainage; signing and pavement marking design and plans production; structures design and plans production for the two 1,700+ foot long Category II third-level steel box girder bridges at the SR 417 interchange; mainline tolling gantry design; environmental permitting; utility coordination; subsurface utility exploration; and survey and mapping services.

This project involves the widening and/or reconstruction of Florida’s Turnpike (SR 91) from Osceola Parkway to the Beachline Expressway. The specific limits for this project are the northbound and southbound lanes from M.P. 247.770 to M.P. 255.499. Within this proposed 8-lane section of SR 91, the northbound and southbound directions each will consist of two 12-foot express lanes separated from two 12-foot general purpose toll lanes by a 4-foot buffer with express lane markers. Other improvements associated with this project include the construction of three ramps at the SR 91/SR 417 interchange.

These ramps include Ramp A2 (northbound SR 91 to southbound SR 417) which includes the construction of a 1,882 ft long Category II/third level steel box girder bridge structure, Ramp C2 (southbound SR 91 to northbound SR 417) which includes the construction of a 1,715 ft long Category II/third level steel box girder bridge structure, and Ramp D1 (southbound SR 91 to southbound SR 417). Improvements associated with this project also include the reconstruction and/or widening of the Osceola Parkway and Orlando South Interchange exit/entry ramps, including the replacement of the existing ramp bridge at the Orlando South Interchange.

Other proposed bridge improvements include the replacement of the SR 91 bridges over the Central Florida Rail Corridor and over Central Florida Parkway/CSX Railroad Spur, and the replacement of the existing Orange County roadway overpasses at CR 527 (Orange Ave) and Taft-Vineland Road. Other improvements include signing and pavement marking related to the implementation of express lanes, drainage and stormwater management improvements, highway lighting within the interchange limits, upgraded ITS infrastructure, and the addition of three tolling facilities.
