R1 · R2 · R3
The date of definition of this route is in the 1964-1966 time period. It appears that in 1970, it was adopted as a state highway, becoming Route 243.
Kaiser Road from Route 177 to Eagle Mountain (11.26 mi)
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.
