Tuesday is the last day that humans will collect tolls on the Golden Gate Bridge as the iconic span becomes the first in California and one of the few in the world to convert to electronic taking.
The last toll-takers are scheduled to wrap up their shifts around midnight Tuesday.
By the morning commute Wednesday, motorists heading southbound on the span are expected to roll through the toll plaza without stopping to pay.
"Just ride through. Do not stop," said Mary Currie, a spokeswoman for the Golden Gate Bridge Highway and Transportation District.
A 27-foot LED sign atop the toll plaza will remind motorists to keep moving. Currie said bridge officials may also employ a loud-speaker or station themselves near traffic to wave people through.
