Historical Tour of old US 99
Castaic Creek / Hasley Canyon Road
Shown here, US 99 crosses Castaic Creek (53-09). This bridge dates back to 1931 when US 99 was being widened to three lanes and realigned from Saugus Junction to Castaic. In 1951, this section of highway was widened from three lanes to a four lane expressway. When I-5 was built here in 1968, the 1951 bridge across this creek was demolished. Its location is beneath the southbound lanes. This, however, is not the only alignment through here. The piers visible in the photo below are from a bridge that was built in 1916. It was a through-girder type bridge that was also commonly used for railroads. I will try to get a photo of the old bridge here soon.
