Cutting and Capping Highways

“Highways lids, i.e. ‘Cut-and-cover tunnels’ can be thought of as little more than extremely wide bridge structures built over a depressed freeway. This allows a freeway to be completely hidden from view as it courses underneath a neighborhood. Furthermore, the area on top of the covering structure can be utilized as urban space such as parkland.” (source)
