We understand from the passage that, though motorists would have much preferred a fixed bridge, ----.
When it came to replacing the bridge at John's
Pass, there were certain special problems to be
taken into consideration. The previous bridge had
had a life span of only 30 years, but in that time the
currents had caused extensive damage. But a more
serious problem connected with the currents is that
the bridge has to open on demand, rather than on a
fixed schedule. Currents at the inlet are particularly
fierce, and making boats wait would be too
dangerous. This unpredictability makes life even
tougher for motorists. Yet a fixed bridge would make
a stretch of the Intracoastal Waterway impassable to
boats taller than 65 feet, so that option was ruled out
almost immediately. When an examination of the
bridge's records showed that increasing the height
would reduce the frequency of closings only slightly,
the state decided to build a new drawbridge with the
same height as the old one.
