RIVERSIDE - Reports of concrete falling from the Riverside (91) Freeway prompted authorities to shut down an underpass in Riverside on Wednesday, where Caltrans engineers were expected to conduct an inspection.
Around 12:45 p.m., Riverside police completely closed Pierce Street at the 91, as well as the eastbound offramp to Pierce, after receiving calls that chunks of concrete were landing on the roadway.
The closure led to a significant bottleneck as officers turned motorists around, according to reports from the scene.
California Highway Patrol Officer Travis Monks told City News Service that a CHP officer had gone up and down both the east- and westbound sides of the freeway several times in search of possible damage, but found nothing. The freeway was expected to remain open, he said.
According to a Caltrans District 8 spokeswoman, an engineer and regional superintendent were preparing to conduct an inspection to ensure the structural integrity of the freeway.
