I am working on a project at UNC on Winston-Salem, NC, and am looking for examples of crossings of highways that were succesful in knitting together neighborhoods on both sides. The particular situation here is that there is a historic, walkable village (Old Salem) on one side of the highway, and the downtown that is trying to be somewhat walkable on the other. We are helped in the situation that the highway is an early one, and therefore not that wide (four lanes, some 80-90' according to my measurements on google earth) and that it is in a natural (?) depression already - the crossings are at grade.
Nevertheless, the urbanity of either side has failed to connect across the highway. This surely has to do with land use choice near the highway - it looks like parking lot and blank space, though I imagine it also has to do with the types of streets that are crossing the highway.
So, I was wondering if people have ideas of urbanity and the urban-feeling pedestrian experience bridging a highway. I am afraid that, at least in the short-term, removing the highway is not an option, and neither is a big-dig-style burial. Instead, I am thinking of the Mass Pike near Copley Square in Boston's Back Bay, and perhaps the bridging between the new town and the old town in Edinburgh, or even more radically, Cowgate's crossing under Southbridge, in a fantastic piece of urbanism in Edinburgh.
Any other examples, or ideas of strategies?
Thank you very much.
