I think we are at 400 km (240 miles) or bike paths, bike lanes, and recreational trails here in Edmonton and we plan on increasing our bicycle infrastructure by over 100% and equipping every bus with bike racks.
Not bad for a city that spends a good deal of it's time buried under snow.
Ridership here is way up (we hit 1% or 25,000 trips per day this summer) but we have a long ways to go to come close to Portland's ridership of 6-7 %.
