Ventura Boulevard is one of the primary east–west thoroughfares in the
San Fernando Valley,
California,
USA; as it was originally a part of the
El Camino Real (the trail between Spanish missions), Ventura Boulevard is one of the oldest routes in the San Fernando Valley. It was also
U.S. Route 101 before the
freeway (which it is parallel to for much of Ventura Boulevard's length) was built and it was also signed as Business U.S. Route 101.
