New 91 Lanes to open March 20 – Expect Heavy Work to Prepare for Opening

Mark your calendar! The Riverside County Transportation Commission has set March 20 as the opening date for the new 91 Express Lanes and general purpose lanes in Corona. Westbound lanes are planned to open by 4 a.m., and eastbound lanes are planned to open by 5 a.m..

RCTC’s $1.4 billion 91 Project extends the 91 Express Lanes eight miles to Interstate 15 in Riverside County, adds general purpose lanes between the 71 and I-15, and provides a tolled express connector between the 91 and I-15. The project also built or widened 32 bridges, improved five interchanges, and realigned and repaved local streets.

Construction began in July 2014. The project used an innovative design-build method, which accelerated project delivery by three to four years. Typically, a project of this size and complexity would take approximately seven years to build.

“RCTC made a promise to open the new lanes in spring 2017, and March 20 is the first day of spring,” said RCTC Executive Director Anne Mayer. “We are proud to deliver on our promise and equally proud of this major infrastructure investment for Corona and the region,” she said.

During the next 10 days, crews will be working night and day to prepare the new lanes for opening. Motorists should expect multiple lane closures and ramp closures on eastbound and westbound 91, with particularly significant work occurring between Thursday, March 16 and Sunday, March 19. Drivers should expect delays of at least one hour when traveling through the project limits on March 19 and are encouraged to allow extra travel or to avoid the area by using State Route 57 and State Route 60 as alternate routes or to travel via Metrolink.

Although the new lanes will open on March 20, construction work will be ongoing until the fall, with periodic closures required. Information will continue to be available through the project website,, the project helpline, 877–770–9191, the project email, and social media.
