FRA-71-17.16/FRA-670-4.19

This $200 million design build project involves the improvement of safety and operational efficiency of the I-670/71 Interchange. Goals included providing a multimodal solution for the interchange and surrounding streets, access points, pedestrian facilities, and aesthetic enhancement to support the City of Columbus’ Complete Streets philosophy. The RFC (Released for Construction) plans were completed in a nine (9) month period for all of the drainage and SWPPP design, seven bridges (which included a 1000’ long flyover structure), and twenty-six retaining walls. The wall types were of the MSE, CIP, and T-Type. ELR also provided Geotechnical Engineering needs for the entire project.
