To facilitate work on a new transition bridge, southbound Interstate 15 will be shut down at the Riverside (91) Freeway beginning tonight in Corona.
According to the Riverside County Transportation Commission, the southbound side of the 15 will be shut down every night this week between 10 p.m. and 5 a.m. No closures are planned on Saturday or Sunday nights.
Drivers will have to detour into Corona via McKinley Street to get back to the 15, using a designated route.
The closures had been scheduled last week but were canceled when the rain storms hit.
Crews are working to complete work on a wider connector bridge, featuring an express lane, between the 15 and 91, according to the RCTC.
Motorists will be required to observe lower speeds while traveling in the construction area — or risk fines.
The work is part of the $1.3 billion “91 Project Fast Forward,” which got underway in early 2014. The project entails widening the east-west corridor between the Orange County line and I-15, with new traffic lanes and ramps, as well as additional shoulder space and expanded surface streets in the vicinity of the freeway.
