CORONA, Calif. - Motorists are warned to avoid state Route 91 in Corona this weekend as all lanes are shut down while crews demolish a bridge as part of a freeway widening project.
The 55-hour closure, dubbed "Coronageddon" to help get the word out, begins Friday at 9 p.m. for a six-mile stretch between Interstate 15 and state Route 71. Transportation officials hope to have the 91 reopened in time for the Monday morning commute.

Workers will bring down the Maple Street bridge, erect a support structure for an eventual ramp and pave some lanes.
Residents are urged to ditch their cars and take Metrolink, which will double its service between Corona and coastal destinations.
The $1.4 billion project began in 2014 for the vital link between inland Southern California communities and Orange County.
