The following proposed improvement concepts are recommended to move forward to the environmental review process:

• The pink concept, which would extend eastward between Del Mar Boulevard and University Boulevard
• The orange concept, which would extend eastward between Del Mar Boulevard and University Boulevard, reconnecting with the existing US 59 alignment further east
• The purple concept, which would maintain the current US 59 alignment eastward of Saunders Street
• The green concept, which would extend eastward between University Boulevard and Lakeside Boulevard

The No-Build Concept remains an option for consideration. Under this scenario, no new improvements would be constructed.

Proposed Typical Sections and Roadway Footprint

A 400-foot right of way is recommended if the US 59 Corridor is expanded to a freeway, with a reduced footprint of 340 feet in certain locations where needed. The existing corridor has a 150-foot right of way.

The typical freeway section would consist of two 12-foot travel lanes in each direction with four to 10-foot inside and outside shoulders and two lane (each 12 feet wide), one-way frontage roads on either side of the mainlanes.

Key Findings

Generally, the Pink Concept and Orange Concept are the least impactful of proposed concepts for future consideration. All proposed concepts reduce crash rates and conflict points, though their ability to do so is constrained by existing and proposed development.

Two potential residential displacements are anticipated for the Pink, Orange, and Green Concepts. The Purple Concept displaces 19 businesses, while the Pink, Orange, and Green displace one business. These proposed displacements can be viewed on the public meeting roll plots (linked above).

The Purple Concept would potentially displace more future developments, serve more local traffic which produces a lower level of service, and require more curves which generally make the roadway less safe for drivers, especially freight.

The Green Concept is the shortest of all proposed concepts. It also has the most substantial impacts to existing lakes and floodplains. All proposed concepts would involve construction in wetlands and an action in a floodplain.

The Orange Concept is the least impactful to existing and potential wetlands within the study area right of way.

US 59 Feasibility Study Timeline

The US 59 Feasibility Study is currently conducting a public meeting and comment period before developing the final Feasibility Study Report, which is anticipated to be complete by the end of the year.

The next phase in the project development process is environmental review and schematic design. This process depends on many factors including environmental classification and takes an average of two years to complete. Final design, right of way acquisition, and utilities coordination take another two to four years to complete on average. Phased construction cannot begin until full funding is secured. This project is currently partially funded.
