The primary purpose of this Interchange Modification Report (IMR) is to update the analysis conducted as part of the 2012 PD&E Study for I-75 (SR-93) from Palmetto Expressway (SR-826) to I-595 (SR-862) and develop a concept that includes a Park & Ride (P&R) facility while maintaining or improving the traffic operations LOS of the 2012 PD&E Preferred Alternative. The 2012 PD&E developed six alternatives that included a P&R facility on the southeast quadrant of the intersection. However, these alternatives could not achieve adequate LOS D or better at the SR-93 (I-75) NB Ramp Terminal intersection with SR-820 (Pines Boulevard); Therefore, the 2012 PD&E Preferred Alternative did not include a P&R facility.
It is in the national interest to preserve and enhance the Interstate System to meet the needs of the 21st Century by assuring that it provides the highest level of service in terms of safety and mobility. Full control of access along the Interstate mainline and ramps, along with control of access on the crossroad at interchanges, is critical to providing such service. Therefore, the Federal Highway Administration's (FHWA) decision to approve new or revised access points to the Interstate System under Title 23, United States Code (U.S.C.), Section 111, must be supported by substantiated information justifying and documenting that decision.

The 2012 PD&E developed six alternatives that included a P&R facility on the southeast quadrant of the intersection. However, none of these alternatives achieved adequate LOS at the SR-93 (I-75) NB Ramp Terminal intersection with SR-820 (Pines Boulevard); hence, the PD&E Preferred Alternative did not include a P&R facility. Consequently, the primary need of this IMR is to develop a concept that includes a P&R facility while maintaining or improving the traffic operations LOS of the PD&E Preferred Alternative.
