Can You be Cited for Jaywalking on a Street That is Closed to Traffic

My question involves criminal law for the state of: California
I received a citation for jaywalking (walking in the roadway) on a street that had been barricaded on both ends with sawhorses and marked police cars. Is this a valid citation? Thanks in advance for your help.

Yes. You can't cross the street between two intersections controlled by a stop-light or stop-sign. Cities also have local ordinances which, at the very least, increase the fine amount.

Ok but is it relevant if the street is barricaded to prevent vehicle traffic?

California Vehicle Code section 21955 states: “Between adjacent intersections controlled by traffic control signal devices or by police officers, pedestrians shall not cross the roadway at any place except in a crosswalk.” It does not contain any exceptions for when there is no traffic or traffic is barricaded.
