HALIFAX - The historic streets of Halifax—the narrow downtown streets, the more-than-four-street intersections, the super steep streets—predate the automobile by 150 years, and although in the last 100 years they may have belonged to the cars and trucks, in the next 100 years they may not.  Sometimes, however, it seems like there is no end in sight for the automobile, with HRM's car-centric existence fueling the way the city sounds, the way it feels, and the way it behaves.  Hello Bayers Lake Shopping Center!  Good day Dartmouth Crossing! But imagine the city, our busy, crowded streets, designed for transportation alternatives, for cycling, say.  What might Halifax look like? For starters, I doubt very much that there would continue to exist a bicycle path that resembles the MacDonald Bridge bicycle on-ramp.  Let me explain: What downtown Halifax lost to the Cogswell interchange, I would argue that the cycling community has lost in the MacDonald Bridge bike path.  Cyclists who cross the MacDonald Bridge by bike know the problem, but for those who don't, imagine a peaceful ride across the MacDonald bridge on your very own urban bike path.  Nice hey?  Now imagine that you are forced to descend four stories and then ascend those same four stories before you can access/exit the Halifax side of the bridge. Welcome to Halifax’s MacDonald Bridge Bike Path.
