A nice and detailed model of 'open spandrel deck' arch bridge for a highway traffic with four traffic lanes.
This type of bridge is best suited for crossing valleys, canyons, rivers or lakes because they blend nicely and have littlest impact on the environment.
The total bridge length (including abutment) is 476 meters (1562 feet). The total bridge width is 21.6 meters (71 feet). The bridge has an arch span of 243 meters (797 feet) with a rise of 55.75 meters (183 feet) giving it a rise-to-span ratio of 1/4.36. The bridge has two separate 7.7 meters (25 feet) two-lane roadways as well as sidewalks on both sides.
