I-805 at State 52

Shown here, I-805 (upper) crosses the 52 freeway (lower) at San Clemente Canyon. Built in 1972, it formed the eastern terminus of the 52 for many years. In 1987, was extended to Convoy St. I-805 also follows the former boundary between the San Diego Mission Lands (east) and San Diego Pueblo Lands (west). This becomes quite evident in the North Park area where Boundary Street runs quite close to the freeway.

1929 culvert beneath I-5, at the lower left of the photo. Taken 2022.

Hidden below I-5 just north of Valencia Blvd next to a drainage basin, a bit of US 99 history remains in Santa Clarita, California. A culvert, dating to 1929, has survived through an expressway upgrade in 1949, freeway construction in 1967, bridge replacement construction in 2001, and current widening work in 2022. How much longer it will last is unknown but so far it has withstood the test of time.

1912 / 1933 Greenspot Road bridge over the Santa Ana River

The Greenspot Road bridge, locally known as the “Erector Set Bridge” has an interesting history. It was originally built in 1912 located near Victorville at the Mojave Narrows. In 1932, the bridge was dismantled and replaced with a wider span for US Highway 66. In 1933, San Bernardino County purchased a portion of the span and rebuilt it over the Santa Ana River between Mentone and Highland. The bridge remained in general use until 2015 when it was bypassed by a new bridge to the west. Today, the bridge is a part of a bicycle trail along the Santa Ana River.

To get to the bridge, use either the 5th St / Greenspot Road exit on State 210 (Exit 83) from the west or via State 38 (Mill Creek Road) and Garnet St from the east.

1920’s postcard of the Ridge Route near Castaic, CA

The Ridge Route on US 99 between Castaic and Gorman was a very twisty roadway when it first opened. All told, there was about 39,600 degrees of curvature over the approximately 30-mile route, enough to go in 110 circles. The state gradually worked to alleviate this headache by straightening curves whenever possible. Some curves were merely daylighted where others were completely bypassed. In the case of the Callahan Line Change, as shown in the postcard above, the road was shifted to change eight sharp curves into one gentle curve. The work here was completed in 1926. In 1933, the roadway would by bypassed altogether by the Ridge Route Alternate.

Badlands along US 60 in 1935. Courtesy – Caltrans

In 1936, US 60 was realigned between Moreno Valley and Beaumont. This realignment took the highway off of the Jackrabbit Trail and put it on a new alignment through the Badlands. This is the same alignment State 60 follows today.

This photo from 1935 shows the immense cuts and fills that were necessary for even the two-lane version of the roadway. In 1956, the roadway was widened to a four-lane expressway, further deepening some of these cuts. Work is currently underway to make this section six-lanes, with the outer lanes being truck-climbing lanes.
