Part of the interchange connecting the Riverside (91) Freeway to Interstate 15 in Corona will be shut down tonight, so motorists should expect delays and plan to take alternate routes, officials said.
Crews working on the 91 freeway expansion project will modify connector ramps that allow motorists to transition from southbound and northbound I-15 to the westbound 91.
The connectors will be closed from 9 p.m. to 8 a.m. Sunday, according to the Riverside County Transportation Commission. Detour signs will direct drivers beneath the interchange, bypassing the road work, and into the city of Corona, where they will be able to join the westbound 91 via McKinley Street. Motorists were advised to be prepared for slow traffic along the detour route.
Additional closures are planned at the interchange in the coming months, officials said.
