FOR IMMEDIATE RELEASE
Marine Way Undercrossing
We are advancing the Marine Way extension and undercrossing to improve access and traffic circulation in and around the Great Park. While Marine Way runs along the southern edge of the park, there is currently no direct rail crossing or direct road access into the Great Park from Marine Way and Barranca, where Marine Way currently ends.
The project will create a new rail undercrossing at Marine Way, providing a direct connection between the Great Park and the Spectrum area - the nearest crossings are currently located at Sand Canyon Avenue and Alton Parkway. The Marine Way road extension will connect the two existing termini of Marine Way at the Great Park, and Marine Way and Barranca. These new routes will reduce travel distances, ease congestion, and help save time and fuel for drivers.
Once complete, the project will enhance safety for pedestrians and bicyclists, support walking and biking with new connections, and reduce greenhouse gas emissions by cutting down on vehicle trips.
Construction is underway, with major work continuing through 2026 and full project completion anticipated in 2027.
