The FDOT is conducting the I-75 PD&E study in conjunction with Hillsborough County and the Federal Highway Administration (FHWA). The study will document information necessary for the FDOT and FHWA to reach a decision on the type, design and location of improvements to I-75.

Based on long-range planning, projected population and employment growth, and projected traffic volumes, the Hillsborough Metropolitan Planning Organization (MPO) has made this a priority project in Hillsborough County. The Hillsborough County MPO’s 2035 LRTP Needs Assessment Map, adopted on December 9, 2009, indicates the need for managed lanes throughout the length of the project and a total of 12 travel lanes from south of US 301 to I-4 and ten travel lanes from I-4 to north of Fletcher Avenue.

This portion of I-75 was evaluated in the Programming Screen of the Efficient Transportation Decision Making (ETDM) process as Project # 8002 in 2007. During preliminary planning for this project through the FDOT’s ETDM screening process, agency comments were received. As a result the Federal Highway Administration has determined that this project qualifies as a Type 2 Categorical Exclusion.

RECOMMENDED TYPICAL SECTIONS

The Recommended Build Alternative typical section consists of 12 travel lanes with three 12-foot general use lanes in each direction and three 12-foot special use lanes in each direction. The proposed typical section would provide a minimum 22-foot median that would include a 2-foot concrete barrier wall and 10-foot paved shoulders on both sides of the wall. A 6-foot buffer, consisting of paint and/or plastic pylons, would separate the SULs from the GULs. Under the Recommended Build Alternative, the proposed widening of I-75 would mainly occur to the inside, within the existing median. The widening of I-75 can be constructed within the existing right of way. Additional right of way will be required, however, for interchange enhancements, stormwater management facilities, and floodplain compensation sites.
