Holborn Viaduct

A rough photogrammetry capture of the road bridge called Holborn Viaduct over Farringdon Street, London with stairwells in each corner. Model cross-sectioned just above the height of the bridge. Some of the the gates under the bridge are access points to the cable and sewer tunnels under this part of London. Under Farringdon Street is the River Fleet, the valley of which created the need for the bridge itself.
