Freeway lid

Deck bridge on top of a highway

A freeway lid is a type of deck bridge built on top of a controlled-access highway or other roadway. It is commonly used to create new parkland in urban areas, but can also be used to house buildings or other heavy structures like convention centers. In some locations, the terms stitch or cap-and-stitch are used to describe overpasses containing widened bridges that accommodate wider sidewalks or small amenity space beside the roadway above the highway.
