The Rosedale Highway exit on Southbound Highway 99 is scheduled to shut down for about two hours Wednesday morning. 

According to Caltrans, the off-ramp will be closed from 9-11 a.m. Wednesday. 

Caltrans says the off-ramp will be shut down for "electrical maintenance". 

Caltrans says the closure could be longer, depending on weather conditions and "uncontrollable events."
