  • State College Boulevard Undercrossing Opens

    Attention motorists! The new State College Boulevard Undercrossing in Fullerton opened to vehicles, cyclists and pedestrians the morning of November 1. Click here for more details.

    The City of Fullerton and the Orange County Transportation Authority (OCTA) are constructing a vehicle undercrossing at the intersection of State College Boulevard and the Burlington Northern Santa Fe Railway. The roadway will be lowered between Santa Fe Avenue to the north to approximately 500 feet south of Valencia Drive to the south.When completed, the project will move cars safely and smoothly under the railroad tracks, enhancing safety and boosting mobility.

    In early 2015, State College Boulevard closed to motorists. During this closure, drivers are being detoured to Acacia Avenue, which will be temporarily striped to a four-lane roadway.
