A big rig crashed into the left shoulder divider of the eastbound Route 60 Rubidoux Boulevard off-ramp in Jurupa Valley, spilling oil onto the roadway and causing traffic delays Thursday.
The crash at 8:40 a.m. temporarily closed down the off-ramp, Caltrans announced on Twitter.
The off-ramp was expected to be closed until crews could clean up the oil spill, according to the California Highway Patrol traffic information page.
Only damage to the off-ramp guardrail had been reported.
No injuries were reported and the cause of the crash was still under investigation.
