Great American Infrastructure: Seven-Mile Bridge, FL

Posted by Steve Anderson on Friday, July 13th, 2012

This is the twenty-first in a series of entries celebrating infrastructure achievements in the United States.

What: The Seven-Mile Bridge is one of the longest bridges in America and was at the time of its completion (in 1982), the longest continuous concrete segmental bridge in the world.

When: There are two bridges in the same location that bear the same name.  The first was built from 1900-12 & was destroyed in 1935.  The current incarnation of the bridge (in use), opened in 1982.

– Length: 6.765 miles (just shy of the claim in its name)
– Width: 38 ft.
Longest Span: 135 ft.

Interesting facts: The bridge is something of a star and has been featured in many films, including True Lies and License to Kill.

The Seven-Mile Bridge was supposed to be built in three years, but due to the use of precast, segmental construction in assembly-line fashion, it was completed six months ahead of schedule.
