99 Alert – Calimesa Area

Roberts Road, highlighted in orange, between Cherry Valley Blvd and Singleton Road

A section of US 99 in Calimesa, Riverside County, with concrete dating to 1925, is in danger of being destroyed and forgotten due to developments on the adjacent land. Known as Roberts Road, running for nearly 3/4 mile between Cherry Valley Blvd and Singleton Road, has the last intact and exposed concrete between Yucaipa and Whitewater. This was US 99 from 1926-1937.

As the roadway is to be realigned to the south, we propose making this into a recreational path or at least preserving the contractors date stamps in the paving. This is a treasure that needs to live on.
