At night.
Treasure Island used to be a Naval Base, smack dab right in the middle of SF Bay.
The San Francisco-Oakland Bay Bridge runs right through it in fact.
A new eastern span is being built, and there is currently a temporary S-Curve put in so that the new span can be connected to the tunnel on the island.
This is what it looks like at night (and NO Roger, the water is not leaking out the side of the picture).
Here's the view of SF from Treasure Island where the Naval Base used to be.
It's a two image pano.
Here we're looking down the suspension span of the Bay Bridge, towards SF.
