While Richmond-San Rafael Bridge toll takers were sheltering in place to avoid unhealthy air from a fire burning at the nearby Richmond Chevron refinery Monday evening, motorists crossed the toll plaza without paying.
But the bills were in the mail, a Caltrans spokesman said Tuesday.
The fire, which broke out at the oil refinery at 6:30 p.m., prompted a shelter-in-place order to residents in nearby areas, which affected toll takers at the bridge.
Cash-paying drivers, who drove past empty tollbooths as employees were hunkered down in the toll plaza office, will be billed the $5 toll, Caltrans spokesman Bob Haus said.
"It's handled similarly to when a person crosses without paying," except no fine will be attached to the bill for Monday night's "special circumstances," Haus said.
A camera takes a photo of license plates that cross without paying, and a bill is sent to the home connected to those plates -- usually with a fine reaching about $75, Haus said.
The $5 bill should reach mailboxes in a few days or by early next week, Haus said.
Motorists with electronic FasTrak passes crossed the bridge as usual and should not receive bills or notices, he said.
The California Highway Patrol reported no major incidents on the bridge or span leading up to the toll plaza while the shelter-in-place orders were issued.
The order was lifted around 11:15 p.m., according to the Contra Costa Health Department.
