I-95 (SR9)/ Old. St. Augustine Road Interchange Safety Improvements

WGI was awarded this contract, which was one of three separate safety projects. This project consists of widening southbound loop ramp to accommodate the dual left turn and requires a concrete barrier wall between the southbound exit ramp and the southbound entrance ramp. The project includes the widening of mainline I-95 to provide for northbound and southbound Auxiliary lanes from I-295 to Old St. Augustine Road. The project accommodated all additional drainage and permitting requirements.

The safety study revealed that there are significant traffic queues along Old St. Augustine Road and the I-95 ramps. The most significant queue is along the southbound exit ramp, which extends almost to the end of the existing storage/ deceleration lane. The project includes extending the acceleration and deceleration lanes on I-95, as well as lengthening the dual left-turn storage for the southbound exit ramp.

WGI coordinated with the I-95 widening (SR 9B to I-295) project that extended the necessary lanes through this interchange and reduced the need to extend the acceleration and deceleration lanes. Existing signage impacted by the construction will be relocated. This includes shifting of the southbound I-95 exit cantilever sign.

After final plans were approved by Tallahassee, FDOT requested that WGI prepare Landscape Irrigation Plans to resolve an issue with the Developer. WGI completed plan revisions ahead of schedule and maintained the digital production schedule. This project is complete and scheduled to be let.
