Nighttime ramp and connector closures are planned on the 91 Freeway in the Inland Empire through Friday.
The closures began Monday, May 22, and are expected to last through Friday, May 26. There are no planned closures during Memorial Day weekend, according to Riverside County transportation officials.
The closures are due to the 91 Project, a project that aims to make improvements to the 91 Freeway from Corona to Riverside.
