This bridge is one of the last remaining bridges on old US 99 over the mountains. This is also one of the more interesting bridges along US 99. Half of this bridge, the right side (northbound), was built in 1932 with three lanes. The left side (southbound) of the bridge was added in 1951, bringing the total width to four lanes plus shoulders and a center divider. The guardrails are different on each side of the bridge. On the 1932 side, they are wooden and on the 1951 side, they are metal. This section, from the Piru Creek Bridge to just beyond Pyramid Rock, was the one of the last segments of US 99 to be upgraded to four lanes. It was also one of the toughest as it required a lot of blasting of tough rock and the realignment of Piru Creek.
