The McKinley Street Grade Separation Project is set to change the way you travel through McKinley Street.

City of Corona residents and commuters experience significant traffic congestion daily on McKinley Street. To improve this, a suspension bridge will be built elevating McKinley Street over the BNSF railroad tracks and Arlington Channel. Construction will extend from State Route 91 on the north side to Magnolia Avenue on the south side.

Once complete, the project will relieve traffic congestion, improve mobility and safety for both motorists and pedestrians, as well as improve emergency response times, air quality and noise. Expected project completion is late 2024/early 2025.

71/91 Interchange Project: Upcoming closures allow crews to safely remove support structures above the eastbound 91. The removal process will take place over several weeks, Monday through Wednesday nights, beginning July 15. Additional nighttime lane reductions, ramp closures, and connector closures will occur Monday — Friday nights. The southbound 71 to eastbound 91 will remain open.
