The Interchange Browser provides a web interface to terraserver-usa.com's data archive of aerial imagery from the United States Geological Survey. The imagery depicts vasts regions of the United States with a spatial resolution sufficient for viewing the nation's roads and freeways and their interchange connections.
Most imagery in the archive and in the Interchange Browser originates from the period 1993–1999, while select urban areas have color coverage from 2001–2002. While most interchanges have not changed since the aerial photographs were taken, others have been reconfigured, changing from one type of interchange to another. Additionally, new interchanges and freeways built in more recent years may not appear in the archive and are left without a link in the Interchange Browser.
