I-10 & I-12 College Dr Flyover Ramp Design-Build

The BOH/GEC Team was selected to provide bridge design and engineering services for the planned I-10 and I-12 College Drive Flyover Ramp in Baton Rouge, Louisiana. This project will be funded through the state’s first issuance of GARVEE bonds, which are special bonds that will be repaid over 12 years using federal funds allocated to Louisiana.

Our Team developed an innovative approach to this project that exceeds the project goals established by LADOTD. By realigning I-12 WB mainlines to more closely follow I-12 EB mainlines and eliminating a new Overpass Bridge structure over the existing I-12 WB, our approach eliminates the need to relocate the existing concrete sound barrier near the Bocage and Jefferson Place neighborhoods, greatly minimizing any noise or visual impacts during and after construction. Additionally, our approach allows us to construct the majority of the project without any significant changes to current traffic patterns, which increases worker and public safety.
