The overwhelming majority of people here rely on automobiles to get around, not bikes. I know Anchorage has lots of cyclists, but there are really far too few of you to justify taking high volume traffic lanes away from the majority of citizens in order to accommodate what is basically a hobby in this day and age. Not to mention your idea would not only snarl traffic on NL and Benson, but would also cause traffic throughout town to back up. And honestly those lanes would be more or less unused in the winter, because I'm willing to bet the numbers of active bike riders drops dramatically around Oct-Mar timeframe.
