Here's pictures of another bridge crossing in the Northwest, Highway 99 from Downtown Seattle to Fremont.
Highway 99, as it rolls thru seattle and across the Ship Canal via the Aurora Avenue Bridge, is a six lane, narrow lanes, undivided, no center lane truss bridge with traffic moving at 50-60 miles per hour if congestion doesn't slow it down. To the right of the traffic lanes is a 4 foot wide sidewalk separated from the traffic lanes by an eight to twelve inch curb and a newly installed 4 foot metal barrier railing. The 3 pictures in the top row, and the lower left picture show the Aurora Bridge choices, from the east side walkway.
Would you choose to ride
1) in the lanes of traffic across the Aurora Avenue Bridge? or
2) on the railed and seperated walkway?
The bridge is over a quarter mile long, and traffic also merges at the the approaches to the bridge via high speed ramps. Traffic across the bridge is averaged by the WSDOT of over 100,000 cars a day.
Now, a VC puzzler gambit, is option number 3 - a lower crossing of the Ship canal via Dexter Avenue and the Fremont bridge.
Dexter Ave heads across the lower, Fremont drawbridge that closely parallels the route below the Aurora Avenue Bridge. the 2 far right pictures of the lower row show Dexter Avenue.
The Fremont Drawbridge and Dexter are lower on the hill by about 200 feet. Much lower volumes of traffic, 25-35 miles per hour, two lanes of traffic and bike lanes in both directions.
For the sake of this puzzler, assume all routes will place you across the Ship canal at roughly the same spot, within 5-6 blocks at the North end and within 75 yards on the South end of both Aurora and Dexter. The dexter route is marginally slower.
Where do you position yourself across the Lake Union Ship Canal? and why?
in the Traffic lanes on the Aurora Ave Bridge?
on the segregated walkway on the Aurora Ave Bridge?
Or lower down in the bike lane on Dexter Ave?
