thread_title: Bridge type

message: 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)

====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.

thread_title: Speed of jumper

message: 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)
thread_title: Units

message: If the lead sentence is correct when saying the bridge is "commonly called the Aurora Bridge", is there a good reason that the article title isn't "", per WP:COMMONNAME? —BarrelProof (talk) 15:25, 26 September 2015 (UTC)
replies: text: Yes, we have the same problems with the Ballard Locks. Both should be moved. Interstate 90 floating bridge is probably OK -- in the vernacular the I-90 crossing is one bridge, but the articles cover both the Homer M. Hadley Memorial Bridge and Lacey V. Murrow Memorial Bridge. I'd support a move of both Hiram M. Chittenden Locks and George Washington Memorial Bridge. --Dennis Bratland (talk) 15:36, 26 September 2015 (UTC)
