INLAND EMPIRE – Caltrans is asking motorists to gear up for two major freeway closures this weekend. Getting access to the westbound 91 freeway in Corona could be problematic. Both the north and southbound ramps from Interstate 15 will be closed. It’s part of the ongoing expansion of the 91. Specifically, the northbound I-15 to westbound 91 connector will close from 10 pm on Friday through 4 am on Monday, August 24. The southbound I-15 to westbound 91 connector will close from 10 pm to 6:30 am on August 21, from 11 pm to 8 am on August 22, and from 10 pm to 4 am on August 23. A detour using McKinley Street is advised or avoid the 15-91 interchange when possible. Another closure will impact the 215 freeway near Perris. Northbound I-215 between Ethanac Road and Highway 74 East: • Full closure from 10 pm on Friday, August 21 to 7 am on Saturday, August 22. Southbound I-215 between Highway 74 East and Ethanac Road: • Full closure from 11 pm on Saturday, August 22 to 6:30 am on Sunday, August 23. Those closures will facilitate emergency repairs made necessary by an ongoing widening project on the 215.
