Matt,
If you are ever over in New York State, visit the Erie Canal bridges. Same type of lift, but much older and much cooler. Example: http://www.historicbridges.org/bridges/browser/?bridgebrowse...
Wow! Very different--and very cool! Color me surprised; I stand corrected! I'll definitely have to go one of these days and take a look at it for myself.
Actually, I think it is a vertical lift bridge. Milwaukee has some that rise out of the ground like the Erie Canal bridges. In some of these construction photos, the bridge was repaired in the raised position and so it is visible: http://city.milwaukee.gov/mpw/supportforbusiness/projectsumm...
No, it's a single-leaf bascule.
Is this not a vertical lift bridge?
I would definitely like to see them. Being as I live only 30 miles from downtown Milwaukee, this one would be really easy for me to get to.
