[Click here for a key to the symbols used. Some county routes were constructed with federal funds. These routes are indicated as FAP (Federal Aid Primary), FAU (Federal Aid Urban), or FAS (Federal Aid Secondary). If no funding source is shown, no federal funds were used. Note that while some segments seem to have the same attributes, they may differ in the county-local road number assigned to the segment, or in the Caltrans Map Sheet number.]

County Route R2


Kaiser Road from Route 177 to Eagle Mountain (11.26 mi)


History and Signage Information

This route was defined in 1964.

The route was constructed to Eagle Mountain as Kaiser had a huge mining operation there, north of Desert Center, until it ran dry about 25 years ago -- complete with a dedicated rail line (the Eagle Mountain Railroad) which ferried the loads from the mine to the SP (now UP) main line on the northeast shore of the Salton Sea. The product of this mining was used on the local roads in the area. The high concentration of iron particles accounts for the reddish tint to the rock materials sourced locally. Currently, Eagle Mountain is boarded up and fenced -- you can tell it was a company mining town and some of the machinery can still be seen west of Desert Center on I-10. The local gossip was that the Marines out of 29 Palms were using the site for urban combat exercises, which would explain why it was boarded up and fenced so well.
