Project Overview The goal of the Jeffrey Road Grade Separation Project is to provide a grade separation (roadway undercrossing) for Jeffrey Road at the existing OCTA/Metrolink railroad tracks. The project will allow traffic on Jeffrey Road to cross freely under the railroad tracks, providing for the safe travel of both Irvine residents and visitors. The project is one of the largest Public Works projects ever undertaken by the City. Construction, now underway, will proceed through five phases. The first phase, which consists of constructing a lighted, four-lane detour road and train track detour (shoofly), installing a noise/dust barrier wall at The Meadows Mobile Home Community and a pump station for ground water disposal as well as beginning utility relocation, is underway. Additionally, Jeffrey Road is being widened to three lanes in each direction. Construction begins after 7 a.m. and ends at 3:30 p.m. to mitigate construction related impact on traffic, residents, and business owners adjacent to the project. To limit the impact on rush hour traffic, all traffic lanes will remain open before 9 a.m. and after 3 p.m. Detour Road under Construction Conceptual Rendering Construction is anticipated to take 30 months.
