Former US 99-60-70 San Gorgonio Pass

[Max Rockatansky]

San Gorgonio Pass is located in Riverside County, California in the divide between the San Bernardino Mountains and San Jacinto Mountains.  San Gorgonio Pass is home to several communities which were part of US Routes 99, 60 and 70.  This blog will explore the alignment history of US Routes 99-60-70 within the communities of Beaumont, Banning and Cabazon.  Pictured above as the blog cover is US Routes 99-60-70 facing west on Ramsey Street in downtown Banning during 1952.

Something did occur to me.

Why did U.S. 99 southbound veer east and go along the Salton Sea to end in Calexico, instead of following the old Pacific Highway all the way to San Diego (as Interstate 5 does)?

The corridor was occupied by US 101.

I used to work on Ramsey St. The downtown doesn't look all that different.

There were US 60 shields greened out on I-10 until 2020.

I used that gantry for our blog on CA 60 when grabbed some photos back in 2019.  Most of the older cover plate shields have to disappeared in the post-SB1 Caltrans network.

I saw the movie Tremors (in the late 80's sometime?) in that Fox Theater on Ramsey Street pictured from 1937.

There was another one on the 6th St approach, though it wasn't quite as obvious as those. It also had 70-99 shields next to the I-10, but those were also greened out.
