There are 1970s-style barriers separating Charles Street and Rustat Road. This means that the large numbers of cyclists heading in both directions often have to give way to each other. These barriers need replacing by a removable bollard in the centre of the route, so cyclists can easily pass on the correct side as they would any other traffic island but cars can't get through. This is a literal barrier to easy safe convenient cycling and has no place in 21st Century Cambridge. Especially when there is an easy solution around it.
