I just took part in a forum with video feeds between Anchorage and Fairbanks on our new attempts at a statewide Bike/Pedestrian plan and the subject of winter maintenance of sidewalks and bike paths was a topic that got a lot of attention. The complaint was that both sidewalks and near-to-the-road bike paths become nothing more than a dumping ground for snow removal. One of the issues at the bottom of it, as suggested to me later, is the problem with the laws that require that IF you plow/clear a walkway it has to be done to certain specifications. Disabled people in particular have a right to use such paths and clearing paths to that extent is virtually impossible so in most cases the paths and many sidewalks are simply not touched. In Fairbanks our mulituse paths become snow machine trails in the winter which for the most part, is fine with fat tire bikers. Having spent a fair bit of time in Anchorage, I would not say it has extensive bike lanes. The map may look good but if you spend a week riding around town in Anchorage and then spend a week riding around town in Tucson you'll find out what extensive bike lanes means. While it's true that there are some decent multiuser paths that wind around town they are heavily used by families and runners and aren't really appropriate for cyclist rolling at 20mph. It's not a bad place if you like to ride slow and easy but for serious cyclists it's a pretty dismal town IMHO.
