Development in some places is inevitable. How some have lasted as long as they have and being relatively untouched is rather amazing. A section of US 99 known as The Old Road in Santa Clarita between Castaic Junction (Route 126) and Magic Mountain Parkway will be widened in the very near future with two historic bridges being replaced. Los Angeles County announced that the work is finally funded and will commence soon. The 1929 Santa Clara River Bridge and Santa Clara Overhead will be replaced likely starting in the next year or so. The remaining section, a rare section of 1948 expressway with oleander in the median, will be replaced with a six-lane generic roadway.
Use this opportunity to get as many photos and video of what remains! We need to do what we can to preserve the history of US 99 for the future however we can.
