The Riverside County Transportation Commission (RCTC) and the Southern California Regional Rail Authority (Metrolink) have scheduled a weekend closure of the 91/Perris Valley Line in the cities of Perris, Moreno Valley, and part of Riverside on June 22 and 23. Metrolink service will be impacted at the Perris-South, Perris-Downtown, Moreno Valley/March Field, and Riverside-Hunter Park Metrolink stations. During the closure, these stations will not have passenger rail service. Metrolink will provide alternate transportation to passengers who need to get to destinations serviced by the 91/Perris Valley Line.

Riverside Transit Agency and other transit services around the affected stations will run on regular Saturday and Sunday schedules. Metrolink service from the Riverside-Downtown, Riverside-La Sierra, Corona-North Main, and Corona-West stations will operate on the regular Saturday and Sunday schedules.

The two-day shutdown is required to allow crews to safely conduct system tests of infrastructure enhancements related to the Moreno Valley/March Field Station Improvements Project. RCTC and Metrolink value our passenger rail riders and appreciate their patience during the weekend closure.

Construction began on the Moreno Valley/March Field Station Improvements Project in October 2022. Key elements of the project include:

• Adding a second passenger train platform;
• Extending the existing platform to accommodate the length of the standard Metrolink six-car trains; and
• Upgrading 2 ½ miles of track for the future nine-mile double-track corridor south of the station.
