ƒ Improvement Project 2. Diverging Diamond Interchange (DDI) at I-75/Gibsonton Drive. Provide a DDI at the I-75/Gibsonton Drive interchange. Converts the existing northbound I-75 ramp terminal from unsignalized to a two-phase signal. (FDOT Project Status: Design is scheduled for 2025) ƒ Improvement Project 7. US 301/Symmes Road Intersection Operational Improvements. Provides signal timing update to improve the delay of the minor approaches on Symmes Road, while encouraging the northbound through movement. ƒ Improvement Project 8. US 41 Widening from Kracker Ave to SR 676. Widen US 41 from four to six lanes from Kracker Avenue to SR 676. (FDOT Project Status: PD&E study complete; design not yet underway) ƒ Improvement Project 9. Combine Mathog Road and Alafia Trace Boulevard intersections on Gibsonton Drive. Combine Mathog Road and Alafia Trace Boulevard into one intersection. Provide necessary geometric and signal timing changes. ƒ Improvement Project 10. Gibsonton Drive Widening from I-75 to US 301. Widen Gibsonton Drive from four to six lanes from I-75 to US 301. ƒ Improvement Project 11. Balm Riverview Road/Boyette Road Intersection Operational Improvements. Provides signal timing update to improve the delay of the minor approaches. The combination of these improvement projects under the recommended alternative set provides additional capacity on some of the network’s most utilized roadways, while also forming a new connection between them. It is recommended that these individual improvement projects be evaluated in greater detail.

network to areas of high employment outside of the network; in the PM peak period, these vehicles return from these outside employment centers and again must travel through the study area. These vehicles have limited options to traverse north-south and east-west through the study area due to the poor interconnectivity of local roadways and capacity constraints along major arterials. Based on the initial modeling, the project team worked with County staff to understand factors contributing to problem areas and define potential improvement strategies. Consultation with County staff resulted in the identification of a number of potential improvement projects, which were subsequently combined into three different alternative sets. These alternative sets were developed to provide the greatest mobility of vehicles within and through the study area. Performance measures used during the evaluation included volume to capacity (V/C) ratios, intersection delay, and travel time comparisons along the study area’s major roadways. 1.4 Recommendations Of the three alternative sets tested as part of this study, Alternative 3 provided significant V/C improvements, while reducing the delay experienced at intersections with the highest volumes. Of the 11 projects included in the three alternative sets, the seven improvement projects shown in Figure 1 are recommended for further analysis for potential implementation. These were identified as having the greatest potential to improve overall network-wide performance in the AM and PM peak periods, without having to acquire substantial right of way for large scale widening projects. The seven recommended projects are as follows: ƒ Improvement Project 1. Cone Grove Road Connection to Riverview Lakes Lane. Provide a connection between Cone Grove Road to Riverview Lakes Lane, as well as a northbound left-turn to Cone Grove Road from US 301.
