Do many people use the freeway exit at the tunnel in the middle of the Bay Bridge? It leads to former Naval Base "Treasure Island", which if nothing else has spectacular views of San Francisco Bay.
Seems the Navy left, and before its planned re-development what's left has seen better days. I guess it's unique?
The opening north-westward view shows a run down military accommodation block with 6 "wings" off a central stair and service way. Pan down to see a second similar accommodation block at close quarters!
