Highway 101: Carpinteria added a peak-period carpool lane in each direction to the freeway within the City of Carpinteria.  The new lanes tie into third lanes to the south and upcoming projects to the north.


New bridges were built over Franklin and Santa Monica Creeks.  There are freeway on- and off-ramp improvements at Santa Monica Road, Carpinteria Avenue, and Reynolds Avenue. Six new sound walls were constructed to reduce freeway noise for neighbors. 


On local streets, improvements were made to the intersections at Santa Monica Road & Via Real, Reynolds & Carpinteria Avenues, and Bailard Avenue & the freeway ramps.

The bridges at Franklin and Santa Monica Creeks were replaced to accommodate adding a new third lane in each direction on Highway 101 and to improve water flow in the creeks. There are new sound walls on the bridges to reduce neighborhood noise.

The City of Carpinteria and the County worked with Caltrans and SBCAG on a Class I bikeway that provides a connection from Santa Claus Lane to Carpinteria Avenue. This connects the California Coastal Trail between Sandpoint Drive and Carpinteria Avenue for bicyclists and pedestrians.
