[edit] Bridge type
Is this really a cantilever bridge? I thought it was an iron arch bridge. - Jmabel | Talk 08:09, 1 December 2006 (UTC)
[edit] Copyedit
I have rewritten large portions of this article and added inline citations to everything I could. There's still more to expand on with the bridge's history, but I will have to come back to that later. Please comment on the changes here and notify me on my talk page if I have made any errors. Thank you. Cumulus Clouds 20:35, 20 October 2007 (UTC)

[edit] Speed of jumper
The quoted source is incorrect. Time to impact of a free-falling object from a given height near the Earth's surface, disregarding air drag (minor) is approximately h (in feet) = 16t2. Solving for 180 feet gives t = about 3.354 seconds. Acceleration = about 32t feet per second per second, so in 3.354 seconds, the object reaches = 107.32 ft/sec, or about 73 mph vs. the 55 mph reported. Also, their own figures on impact are incorrect. 55 mph = about 81 ft/sec. x 165lbs = 13,365 ft-lb/sec, not the 28,000 quoted. If we use the figures given in this post of 107'/sec x 165 lb, we get 17,655, still far less than 28,000. Need a more accurate source for this section.

- Wow, I never thought to check the math and you're right, that guy was terrible at it. It is unlikely I'll find another section with the same type of information, so if you don't oppose it, I'll just take that part out. Cumulus Clouds (talk) 01:28, 11 December 2007 (UTC)

- Actually, that article from the Journal of Trauma may have it, I'll see what I can find. Cumulus Clouds (talk) 01:30, 11 December 2007 (UTC)
[edit] Units
Intro is given in metric, converted to English. Per the Manual of Style, "# For US-related articles, the main units are US units; for example, 10 miles (16 km)." Since the bridge is in Seattle, Washington, intro should be revised accordingly: US units, with conversion to metric. (infobox also) Unimaginative Username (talk) 09:00, 10 December 2007 (UTC)
