Featured here are projects that have been completed within the North Coast Corridor (NCC). These projects work together to improve our highway and coastal railways — providing more transportation choices.
Several of these projects received funding from the voter-approved TransNet half-cent sales tax, administered by SANDAG, and are the result of your tax dollars at work.

Noise Reduction Pilot
Conducted Next Generation Concrete Surface (NGCS) pilot project on I-5 from Via de la Valle to Lomas Santa Fe Drive to determine whether vehicle noise produced on freeways can be reduced. Completed Late 2012; Cost $2 million.
