Project Overview

Project Bid: $37,304,851.51

Contractor: D & G Construction Inc

The project will add a railroad overpass, add turn lanes at Southeastern Avenue and 26th Street and also 26th Street and Interstate 229 to improve travel times and safety through the area. The project will also improve pedestrian movements across the interstate. 26th Street will remain open throughout the project.
