Members of Milwaukee's biking community want a bike lane on the Hoan Bridge, but Walker's not into it, so it's not going to happen.
He opposed a bike lane on the bridge as Milwaukee County Executive, maintained that posture during his campaign, and has not wavered.
His spokesman issued this statement on Wednesday: "His stance on this issue since January hasn’t changed. Governor Walker supports allowing cyclists ... to use the bridge during the time it is shut down to traffic. He does not support adding a bike lane on the Hoan Bridge."\n
I suspect he's not a biker.
By the way, this video seems to undermine the argument that the bridge can't accommodate bikes because that wouldn't leave enough room for cars during rush hour. And for what it's worth, Vancouver's experiment with a bridge bike lane worked out well.
