Motorists traveling on southbound 71 through Chino Hills are advised to be prepared for weeknight (Monday – Friday) full closures of southbound 71 from Butterfield Ranch Rd/Euclid Ave to the 91. The closures of southbound 71 will begin Monday, March 3 through Friday, April 11 as part of RCTC’s 71/91 Interchange Project. The southbound 71 to eastbound and westbound 91 connectors will also be closed during this time.

The closures will take place from 9 p.m. to 5 a.m., Monday through Thursday nights, and 11:59 p.m. to 6 a.m. on Friday nights. These nighttime closures will allow construction crews to safely remove support structures from the recently constructed new sections of the connector. Additional nighttime lane reduction configurations along eastbound and westbound 91 may also occur during these nightly closures.

To avoid traffic delays, motorists are urged to avoid the southbound 71 and use southbound 57 or southbound I-15 to reach the 91 and other destinations located to the south.

Motorists traveling on southbound 71 will be rerouted to the Euclid Ave off-ramp in Chino Hills. Traffic will be detoured northbound along Euclid Ave to either eastbound or westbound 60, where motorists can travel to either southbound I-15 or southbound 57. Fire, police, and ambulance services will have access for emergency response.

Construction activity is subject to change due to site conditions, weather, or other factors. If the work cannot be completed, it will be rescheduled as soon as possible.

The new non-tolled interchange is designed to improve safety, expand access to other modes of travel, reduce greenhouse gas emissions, enhance traffic flow, and support continued movement of native wildlife through the area. Construction began in 2023 and is expected to be completed later this year. To register for construction updates, text 7191interchange to (855) 793-2625 or sign up through the project webpage.

Motorists traveling through Corona are advised to steer clear of full weeknight closures of westbound 91. Beginning December 2, 2024, the westbound 91 will be closed between the 71 and Green River Road on Monday through Wednesday nights as part of RCTC’s 71/91 Interchange Project. The closures are scheduled through Wednesday, December 18, 2024.

Due to the holidays, no closures will be scheduled from December 20 through January 1, 2025. Closures are anticipated to restart on Monday, January 6, 2025.

The full closure will allow crews to remove more than 40 beams of support structures that span above the westbound 91 lanes. This work requires precision and time to be completed safely. Over the summer, crews completed a similar operation with the removal of support structures over eastbound 91.

Motorists traveling on the westbound 91 and southbound 71 should plan extra time to reach local destinations and businesses in the area. Detailed closure information below:

To avoid lengthy traffic delays, motorists are highly advised to avoid the westbound 91 by using the northbound 71 to westbound 60 to southbound 57 to get around the closure. Construction activity is subject to change due to weather or other factors.

RCTC, in partnership with Caltrans, is reconstructing the 71/91 interchange in Corona. The project will replace the single-lane loop connector between the eastbound 91 and northbound 71 with a new, two-lane, direct connector ramp. The project is anticipated to be completed in 2025.

Motorists making their way south through Chino and Chino Hills should avoid the southbound 71 or be prepared to face heavy traffic delays. RCTC’s 71/91 Interchange Project will require a full weekend closure beginning Friday, August 16 at 10 p.m. through Monday, August 19 at 5 a.m.

The full closure will safely allow crews to pave and stripe the final portion of the newly aligned southbound 71 lanes. During the weekend closure, crews will also perform a traffic switch to shift traffic onto these new lanes. This shift will extend southbound 71, create additional space for the new connector, and allow it to connect to northbound 71 lanes.

To avoid lengthy traffic delays, motorists are highly advised to avoid the southbound 71 and use southbound 57 or southbound I-15 to reach the 91 and other destinations located to the south.

Traveling through Corona at night this summer? There are road closures in the works that you should know about. Motorists driving on the eastbound 91 Monday through Wednesday nights should plan ahead for traffic delays. Starting Monday, July 15, weeknight closures of the eastbound 91 general purpose lanes and Express Lanes are scheduled as part of the 71/91 Interchange Project in Corona. The eastbound Green River Road on-ramp will also be closed at night.

Closures are as scheduled:

• LOCATION: Eastbound 91, from Green River Rd. to Serfas Club Dr./Auto Center Dr.
  • Includes eastbound 91 general purpose lanes, Express Lanes, and Green River Rd. on-ramp
• DAYS & TIMES: Nightly, Monday through Wednesday from 11:00 p.m. to 5:00 a.m.
• DURATION: July 15 – August 14, 2024

The southbound 71 connectors to eastbound and westbound 91 will remain open.

The closures will allow crews to safely remove support structures above the eastbound 91 that were constructed in 2023 and early 2024. These support structures were used to form the foundation of the new connector. The removal process will take place over several weeks, Monday through Wednesday nights, beginning July 15.

Motorists traveling on the eastbound 91 are advised to avoid the area and use northbound 57 to eastbound 60 to the southbound 71. Corona residents may use Green River Rd. to Palisades Drive to Serfas Club Dr./Auto Center Dr. to enter eastbound 91. Motorists should allow extra travel time to reach local businesses, which will remain open. Fire, police, and ambulance services will have access for emergency response.

Construction activity is subject to change due to site conditions, weather, or other factors. If the work cannot be completed, it will be rescheduled as soon as possible.

Motorists heading east should steer clear of eastbound 91 in Corona or plan for heavy traffic delays due to full eastbound 91 closures Monday through Wednesday nights starting Monday, October 16 through Tuesday, November 21.

Closures allow crews to safely construct support structures extending across the entire width of the 91 as part of the 71/91 Interchange Project. Support formwork for the new connector on top of the tunnel will be approximately 30 feet tall and utilize over 200 beams that will be positioned.

The weeknight closures include:

• Full eastbound closure of 91 lanes from Green River Road to Serfas Club Drive, Monday through Wednesday from 11 p.m. to 5 a.m.
• Full eastbound 91 Express Lanes will be closed in Riverside and Orange counties from Monday – Wednesday 10 p.m. to 6 a.m.
• Eastbound on-ramp closure at Green River Road from Monday – Wednesday 10 p.m. to 6 a.m.

During the weeknight closures, motorists can reduce time in traffic by using northbound 57 to eastbound 60 to southbound 71. Please use caution during travel and plan extra time to arrive to your destination. The suggested detour route is shown below.

West Corona residents may utilize the eastbound 91 exit at Green River Road to Palisades Drive or Serfas Club Drive to re-enter to eastbound 91. Access will remain available for fire, police, and ambulance for emergency response.

Construction activity is subject to change due to weather or unforeseen circumstances. Weeknight westbound 91 full closures are expected to begin following the completion of the eastbound support structure work.

The 71/91 Interchange began construction in February and the anticipated opening of the connector is slated for 2025. This project will create a two-lane direct connector between eastbound 91 and northbound 71 to replace the existing single-lane loop connector. This enhancement is intended to improve safety, develop alternative modes of transportation, reduce greenhouse gas emissions, and optimize traffic flow. The $137 million investment is providing 1,677 jobs during construction.

Plan ahead if your schedule calls for driving from the Los Angeles and Orange counties to Riverside County on the 91 the weekend of June 9-12. Motorists traveling east on the 91 this weekend will face heavy traffic due to nighttime closures of the eastbound 91 and closures of both the eastbound and westbound 91 Express Lanes as part of the 71/91 Interchange Project in Corona. The eastbound Green River Rd. on-ramp will also be closed at night.

Closures for the upcoming weekend include:

• Nighttime Full Closures
  • Eastbound 91, Green River Rd. to Serfas Club Dr./Auto Center Dr.
    • Saturday, June 10 from 1 a.m. to 7 a.m.
    • Sunday, June 11 from 1 a.m. to 7 a.m.
    • Monday, June 12 from 1 a.m. to 5 a.m.
• Day and Nighttime Weekend Full Closures
  • Eastbound and Westbound 91 Express Lanes in Riverside County
    • Friday, June 9 at 9 p.m. to Monday, June 12 at 5 a.m.
• Nighttime Full Closures
  • Eastbound 91 Green River Rd. On-Ramp
    • Friday, June 9 at 9 p.m. to Saturday, June 10 at 7 a.m.
    • Saturday, June 10 at 9 p.m. to Sunday, June 11 at 7 a.m.
    • Sunday, June 11 at 9 p.m. to Monday, June 12 at 5 a.m.

The southbound 71 connectors to eastbound and westbound 91 will remain open. The eastbound and westbound 91 general purpose lanes will remain open during daytime hours.

The closures are needed to allow crews to safely lift a large support structure from the 91 median and place it into a 15-foot diameter, 160-foot deep, drilled hole. The cage is 14 feet in diameter, 160 feet long, and weighs 232,000 pounds. The hole will be filled with 700 cubic yards of concrete to build the foundation for one of the columns of the 71/91 connector.

Due to the large size of the cage and the amount of concrete to be transported (more than 70 truckloads), the lanes must be closed during this procedure for the safety of motorists. This series of weekend closures are being carefully planned with the community in mind. These weekend closures reduce the need for a full weekend closure of the eastbound 91 that would significantly impact drivers, residents, and businesses.

To reduce the time spent in potentially heavy traffic, drivers should avoid the area and use the 57 to eastbound 60 to the 71. A map of the suggested detour route is available below.

West Corona residents may use Green River Rd. to Palisades Drive to Serfas Club Dr./Auto Center Dr. to enter eastbound 91. Motorists should allow for extra travel time to reach local businesses, which will remain open. Fire, police, and ambulance services will have access for emergency response.

Construction activity is subject to change due to site conditions, weather or other factors. If the work cannot be completed the weekend of June 9-12, it will be rescheduled as soon as possible.

The 71/91 Interchange began construction in February, and the connector is expected to open in 2025. The project will replace the existing single-lane loop connector between eastbound 91 and northbound 71 with a two-lane direct connector. Once completed, the project is intended to improve safety, expand access to other modes of travel, reduce greenhouse gas emissions, and enhance traffic flow. The $137 million investment is providing 1,677 jobs during construction.

Please share this information with family, friends, and colleagues.

The Point: Expect delays, allow extra travel time, use alternate routes

With many people staying home due to the recent surge in COVID-19 cases, the Riverside County Transportation Commission has scheduled closures on three construction projects in western Riverside County this weekend.

Good weather and fewer cars on the road during this time create ideal conditions for scheduling this trifecta of highway closures for the Route 60 Truck Lanes Project, the Interstate 15 Railroad Canyon Road Interchange Change, and the 15 Express Lanes Project. Motorists who plan to brave the roadways should expect significant delays, allow extra travel time, and use alternate routes. Work will include:

• A full closure of eastbound lanes on Route 60 through the Badlands area between Beaumont and Moreno Valley: Friday, January 8 at 10 p.m. to Monday, January 11 at 5 a.m. Crews for the Route 60 Truck Lanes Project will be relocating 4.5 miles of temporary concrete barrier from the existing eastbound lanes to shift vehicles to the newly paved median. Once lanes are shifted, crews will be able to safely work on the eastbound lanes and outer shoulder. For information, visit rctc.org/60trucklanes, follow @60trucklanes on Facebook, Twitter, and Instagram, or call 866-413-6060.
• A full closure of the southbound I-15 Railroad Canyon Road on-ramp in Lake Elsinore: Friday, January 8 at 8 p.m. to Monday, January 11 at 4 a.m. Crews will be paving the on-ramp and ramp connection to Railroad Canyon Road. The southbound I-15 Railroad Canyon Road off-ramp also will be closed Friday, Saturday, and Sunday nights from 11 p.m. to 7 a.m. Learn more by visiting rctc.org/railroadcanyon, following @railroadcanyon, or calling 877-500-7715.
• A full closure of the southbound I-15 Hidden Valley Parkway on-ramp in Norco: Friday, January 8 at 9 p.m. to Monday, January 11 at 5 a.m. Crews are making drainage repairs along I-15 as part of RCTC’s 15 Express Lanes Project. In addition, the southbound I-15 to westbound 91 connector will be closed Friday, Saturday, and Sunday nights from 9 p.m. to 6 a.m. For details, visit 15project.info, follow @15expresslanes, or call 844-415-9777.

During the past year, RCTC has continued its construction activities across western Riverside County, despite the global pandemic. The agency has eight highway projects under construction, including five that started last year. The projects have created more than 10,000 jobs, helping to offset the economic fallout from COVID-19 and improving the county’s infrastructure, which may lead more businesses to open or relocate to Riverside County.

“As many, many people across Riverside County continue to struggle with unemployment and the reality of this ongoing pandemic, RCTC is helping keep construction workers, engineers, land surveyors, and office personnel employed through these local projects,” said RCTC Chair and Palm Desert Mayor Pro Tem Jan Harnik.
