Construction is officially underway on a major safety and mobility improvement along US 33!

Designed to relieve congestion and reduce crashes, the project will eliminate five at-grade public road crossings and three railroad crossings. Improvements include more than four miles of new roadway, four new bridges, over 2,600 feet of cast-in-place concrete retaining walls, and two new traffic signals along Pickerington Road.

Reaching this milestone required extensive coordination across 103 impacted parcels, representing 58 separate ownerships and three total acquisitions. We’re proud to have helped move this important project!

Take a look at the work now underway from above.
