Los Peñasquitos Creek Arch Bridge

From Wikipedia, the free encyclopedia

The Los Peñasquitos Creek Arch Bridge was completed in 1949. It is a reinforced concrete open-spandrel arch-bridge with an overall length of 434 feet, and an arch span of 220 feet.

The current Los Peñasquitos Creek bridge was first built in 1966 as the southbound lanes of the U.S. Route 395 freeway. The original Los Peñasquitos Creek bridge stayed in use as the northbound lanes.

The current bridge is a prestressed concrete girder bridge, and was completely replaced by widening of the Interstate 15 freeway traffic in 1976. The original arch bridge served as the service road and bikepath.

In 1995, the current bridge was renamed the Cara Knott Memorial Bridge in honor of the 20-year-old San Diego State University student who was stopped and then subsequently murdered by California Highway Patrol officer Craig Peyer near the bridge on the night of December 27, 1986. Peyer was later convicted in the case and is serving a 25 years-to-life sentence in prison.
