In 1955, the first section of the Golden State Freeway opened. It was a short section, running from near Weldon Summit to Foothill Blvd. The freeway was the first major attempt to improve traffic in the Newhall Pass area and it did help for a time. The freeway remained until the early 1970’s when the new I-5 / State 14 interchange was constructed and the old freeway was reconfigured to become the “Truck Lanes”.
Today, the original interchange still remains, though not entirely used. The lower level, formerly the US 6 West to US 99 South connector, is now partially filled in. The second level still carries Sierra Highway with the top level carrying the I-5 Truck Lanes. The Newhall Pass has undergone many changes in its time as a transportation corridor for Los Angeles. This one was but one of those. The photo was taken on November 22, 1955.
