Grange Road has extremely narrow cycle lanes for most of its length, which include traffic calming bollards forcing traffic down to a single lane. While this design does slow traffic, the narrow space for the cycle lane means that trikes have to slow almost to a stop to pass safely -- or in some cases may not fit at all. This forces trikes out into the single centre lane, where cars may not properly give way, and also are the sites of speed bumps and significant potholes. If the lanes were about 20-30cm wider, then trikes could pass without a problem. This issue affects all of the bollards on both sides of Grange Road for its full length, but I’ve highlighted a particularly problematic one since I had to pick a spot.
(In general, the cycle lanes on Grange Road are too narrow for cargo trikes forcing them out into traffic lanes anyway, but it’s the brick bases to the bollards that cause a particular problem.)
