While early construction of the State Route 91 Corridor Improvement Project (also known as The 91 Project) started this spring, full construction began rolling out in July.
Led by the Riverside County Transportation Commission (RCTC), the 91 Project will significantly improve an 8-mile stretch of State Route 91 (SR-91) between Interstate 15 (I-15) and the Orange-Riverside County line.
The project will extend the tolled 91 Express Lanes in Orange County to the I-15, adding a continuous general-purpose lane in each direction and building additional lanes in particularly busy areas. Besides adding lanes, seven interchanges will be rebuilt, and a sweeping elevated ramp will conveniently drop northbound I-15 commuters directly onto new westbound 91 Express Lanes.
As crews ramp up lane striping and construction efforts, drivers will see reduced speed signs of 55 MPH throughout the area. RCTC expects to maintain the current number of lanes in each direction on the SR-91 and I-15 during peak travel hours, except during emergencies or special circumstances.
Safety is the highest priority, so commuters are urged to:
- Slow down and watch for workers and heavy equipment
- Allow extra time to get where they are going
- Tell friends and customers about pre-construction activity
- Take extra care when driving at night and during inclement weather
- Avoid mobile phone use and other distractions
- Watch for lane and ramp closures; use alternate routes and follow detours
- Obey the “Move Over” law. This law requires travelers to move to lanes away from any construction work when it is safe to do so.
This is a short-term inconvenience for a long-term traffic solution. Learn more at www.sr91project.info.
