Ontario CIR Major Pavement Rehabilitation Project
June 26, 2018 – Update

The Cold-in-Place Recycling operation of Ontario Avenue is anticipated to be complete today.  Paving of the final rubberized asphalt surface will complete the pavement rehabilitation Project within the next two weeks.  Striping and marking will be done a few days after the new rubberized asphalt has cooled.

Construction crews will be working late today, Friday, June 22 (until 5:30 p.m.) as well as tomorrow, Saturday, June 23 (7 a.m. to 3:30 p.m.) in an effort to complete the project as quickly as possible. The City would like to ensure all of the Ontario Avenue CIR work is done before the July 4th holiday. 

The most difficult portions of the street are now complete. The operation is now much more efficient which helps get more of the street done in a single day. When all of the reconstruction of the existing pavement is complete, a final asphalt cap will be placed over the width of the street. Final striping will occur shortly after that which will complete the road rehabilitation. The final product will result in a new road surface that could last for over twenty years.

If you have any questions concerning this project, please contact the City of Corona Public Works Department at 951-736-2266 or at publwks@coronaca.gov. We thank you for your patience as we complete the rehabilitation of Ontario Avenue. Please drive safely.

 

Ontario CIR Major Pavement Rehabilitation Project
June 18, 2018 – Update

Starting tomorrow, Tuesday, June 19, construction crews will begin the Cold In-place Recycling (CIR) pavement rehabilitation process. Up until now, construction crews were grinding and removing the cap of Ontario Avenue from Magnolia Avenue to California Avenue in preparation for this work. The CIR process will involve a train of machines about 150 feet long that will remove, recondition, and replace the roadway in a single pass. The train is about the width of a lane but will continue to require two lanes to be closed on Ontario Avenue to ensure the safety of both drivers and workers. This method of roadway re-pavement is more environmentally friendly, cheaper and quicker to complete than other conventional methods.

The train is scheduled to begin tomorrow at the Intersection of Ontario Avenue and Magnolia Avenue at 7:00 a.m. and will travel eastbound to California Avenue around 4:00 p.m. The CIR train will first repave the lane closest to the median and will take a full day to reach California Avenue. The train will then turn around and repeat this process in the westbound direction the following day and so on until the entire roadway has been replaced. During this time there will be short-term closures of some turning movements at intersections while the CIR train works through each intersection. Traffic control will be set up to detour traffic for the 30-60 minutes it is expected to take for the CIR train to cross each intersection and setup the pavement for use by vehicles in all directions again. Traffic signals along Ontario Avenue and detour routes will be modified dynamically from the Traffic Management Center during the entire process to minimize impacts. If you are able to, please continue to use Magnolia Avenue and Foothill Boulevard as preferred detour routes. The CIR process is expected to take seven (7) full working days to complete before moving to the next phase, roadway capping and striping on June 27th.

 

Ontario CIR Major Pavement Rehabilitation Project

The Public Works Department is currently under construction with the Ontario CIR Major Pavement Rehabilitation Project. The project began on Wednesday, June 13 and is expected to be completed in early July. The project consists of performing a major pavement removal and replacement of all lanes of Ontario Avenue from Magnolia Avenue to California Avenue, excluding the recent widening between Kellogg Avenue and Fullerton Avenue.

Please avoid Ontario Avenue from Magnolia to the 15 fwy. Please utilize Foothill and Magnolia as detours. The project will continue for the next couple of weeks during the daytime hours. Staff will actively manage the traffic signal green times to minimize delays. Construction scheduled from 7 a.m. to 5 p.m. daily, through the remainder of the project.

Currently, crews are removing the cap of the roadway which will continue until early next week. After the cap is fully removed, a process know as Cold In-place Recycling (CIR) will be used to grind the subgrade of the street, remix it with new materials and immediately replacing the subgrade back down all in one complete step. This process minimizes waste, time and cost from traditional roadway rehabilitation treatments. The CIR process is expected to take a full 7 days to complete all lanes of Ontario within the project limits and will begin early next week. After the CIR process is complete, the street will be recapped and new roadway lanes and marking will be installed. Completion is expected in early July and will not impact the City's Independence Day event at Santana Park this July 4th. The project is funded by the city's allocation of Gas Tax and Measure A funding sources.

During this process, the contractor may have traffic down to one lane on Ontario in each direction while crews and equipment complete this work. Short-term (a few minutes at a time) blocking of intersections is to be expected and crews work through intersections. Access to all businesses will be maintained except when crews are working in the immediate area. Ontario Avenue will have a rough surface for the next few days until the CIR process is completed. Drivers should take other routes like Magnolia Avenue or Foothill Boulevard as alternatives if possible. Staff will continually monitoring the construction and adjusting traffic signal green times to minimize delays throughout the area as much as possible.

If you have any questions concerning this project, please contact the City of Corona Public Works Department at 951-736-2266 or at publwks@coronaca.gov. We thank you for your patience as we complete the rehabilitation of Ontario Avenue. Please drive safely.
