It should be known that the bridge was shipped in from St. Louis and assembled at it's present location in December 1910. It's the first and oldest vertical lift bridge in the world, and has had three major retrofits to make it better withstand earthquakes (it crosses a major faultline), and to better handle the 20,000+ cyclists it carries per day (outnumbering cars and buses; there's been talk of converting the inside lanes to four additional bicycle lanes, two each way, but not sure how far it got before I moved). Given it's age, and the fact the outside lanes were added originally so trucks and buses could cross the bridge (as the original lanes, inside the bridge superstructure, are narrow), the bridge is old enough that it was originally designed around nonmotorized or horse-drawn crossings, and ultimately ended up having the approaches redone to handle increasingly large vehicle traffic. >> (also, this video of the bridge crossing makes me wonder...how do you >> tag two bike lanes in the same direction? > > > lanes=2, oneway=yes > it's the same as for cars. Otherwise it would be lanes=2, oneway=no Is lanes=* overall number of lanes (in which the example where there's two bicycle lanes would be a total of four lanes) or is it lanes open to all traffic (which would be just two lanes)?
