Project Location Map
The FDOT is conducting a Project Development and Environment (PD&E) Study to consider capacity improvements along SR 8 (I-10) from east of SR 261 (Capital Circle) to west of SR 59 (Gamble Road), a distance of approximately 13 miles. These capacity improvements consist of widening I-10 from four to six lanes in eastern Leon County and western Jefferson County. Interchange improvements will also be considered at SR 261 and US 90 (Mahan Drive).
Purpose and Needs
Roadway Typical Sections
A typical section is a visual representation of the existing roadway elements as they currently are today or a visual representation of what the new roadway elements will be after the improvements. The existing I-10 roadway consists of two 12-foot travel lanes in each direction divided by a 64-foot median with paved shoulders. The proposed typical section includes three 12-foot travel lanes in each direction. The opposing travel lanes are separated by a 40-foot grassed median that includes 10-foot shoulders and a traffic barrier.
Bridge Typical Sections
Similar to the roadway typical sections, the bridge typical section is a visual representation of the existing or proposed roadway elements. The existing bridges typical section consists of two 12-foot travel lanes in each direction with paved shoulders. The proposed typical section includes three 12-foot travel lanes in each direction with paved shoulders. The opposing travel lanes are separated by a traffic barrier.
Interchange improvements are being considered within the project limits and will be evaluated as necessary based on specific needs, issues, and existing conditions. Click on the map below to view the current Build Alternative proposed for the I-10/Mahan Drive Interchange.

As a part of the PD&E process, the Build Alternative has been developed and evaluated for potential environmental impacts, as well as its satisfaction of the project’s Purpose and Need. This Evaluation Matrix summarizes the potential benefits and impacts to widening I-10 between SR 261 (Capital Circle NE) and SR 59 (Gamble Road). As the proposed option continues to be refined, impacts to social, environmental, cultural, and physical resources will be avoided and minimized to the extent practicable.
