LOL, works for me. Other cities have bridges too. In fact San Francisco has other bridges, and I believe some of them are toll free. I may be wrong on that as I’ve only crossed them a few times.
None are toll-free, but you only pay a toll in one direction. Last time I checked it was $5 (Double that for the GG Bridge). When I started driving back in the late '70s, bridge tolls were $0.25. That means that tolls are TWENTY TIMES HIGHER than they were 35 years ago.
