U.S. Highway 101 - San Luis Obispo County

Northbound

Index to U.S. 101:

Site Navigation

U.S. 101 finally enters the Central Coast when it enters San Luis Obispo County, as it passes through Nipomo, Arroyo Grande, Pismo Beach, San Luis Obispo, Atascadero, and Paso Robles. The scenery returns to the coastal imagery of Santa Barbara County, but the freeway quickly retreats inland, leaving the rugged coast to its two-lane alternate, California 1/Pacific Coast Highway. U.S. 101 enters farming country, passing by the vineyards of Paso Robles as it continues its northerly trek, now focused on Monterey Bay and the San Francisco Bay Area.

Northbound U.S. 101 at Exit 189, Fourth Street/Five Cities Drive. The "five cities" were Arroyo Grande, Grover Beach, Oceano, Pismo Beach, and Shell Beach. Of these five "cities," only four remain. Shell Beach was absorbed into the city of Pismo Beach in the late 1970s or early 1980s. This interchange was the location of a shopping area referred to as "Five Cities Shopping Center." The old shopping center was became vacant, and was eventually leveled to create the outlet mall currently located at this interchange. Photo taken 12/23/01.
Northbound U.S. 101 approaching Exit 190, Business U.S. 101/Price Street for Pismo Beach. This sign is somewhat misleading, since it does not clarify which of the five cities' downtowns are reached by using this exit. The bad business loop signing goes without saying. Photo taken 12/23/01.
