Some little know facts (or fictions) about the Coronado Island
bridge:

Some people claim the bridge is designed to float if it's knocked
down in a military strike or an earthquake. This is false, and
seems to come from the days of the bridge's construction. The major
components were shipped by barge from San Francisco to San Diego.
It was called the "floating bridge" in the media in the 1960s
because of this. Part of the myth says floating wreckage could be
quickly towed to the sides so Navy vessels won't become trapped in
the bay.
Another myth is that the bridge was made extra long, with the bend,
and also very tall, in an attempt to use up all the allotted funds.
In fact, there were several reasons for its location and height
that have nothing to do with increasing its cost. On the San Diego
side, the bridge begins in Barrio Logan, a neighborhood with poor
land values -- and low construction costs for the bridge approach.
In Coronado, it joins at the streets (3rd and 4th) that run
directly to and from North Island Naval Air Station, which accounts
for much of the traffic on Coronado.
If you have any other nicknames or trivia, post it!
