Where the Bow River pathway crosses the lower deck of the Centre St bridge is the most dangerous intersection in the entire pathway system. There is no visibility due to the concrete bridge abutments, and the ped/bike walk/don't-walk light is invisible as you approach the intersection. It becomes visible again only in the last 2 seconds before you enter the intersection - and the don't-walk light lasts only 3 seconds before the cars get a green light. Basically, you could have only 1 second to make up your mind to stop, and 1 more second to do it in. Try that with roller blades! In the attached video, you can see the walk light during the first 2 seconds. Then it vanishes from view behind a concrete pillar for the next 12 seconds, and only can be seen again at 0:14, barely 2 seconds before I enter the intersection. Fortunately, the City build a pathway underpass under the bridge to allow users to avoid this dangerous intersection... but they gate that off six months a year! The official excuse is that they remove some of the metal railings along the underpass during the winter because they *might* be damaged by ice floes in the river, and they don't want to endanger you by having to use an underpass with no railing. Never mind that the railings are on top of a low wall that would prevent you from exiting the underpass... onto a dry gravel-bed, or that 3 out of 4 other bridge underpasses have no railings whatsoever at any time during the year. Isn't nice to know that your personal safety takes a back seat to the City's desire to avoid *possible* damage to a few pieces of metal? If you object to this, register your displeasure in the comments, or call your City Hall councillor and demand that the underpasses be kept open year round. We don't close the Deerfoot Trail even though the Calf Robe bridge was so poorly designed that it causes frequent crashes in the winter: it's part of the transportation network, and as such must be kept open year-round. Why must pathway users have their underpasses be closed for much less a safety risk? Does Parks fail to understand that these underpasses are part of the transportation network?
