| 释义 |
The Yalesville Underpass is a 30-degree skew arch bridge carrying the railroad over Route 150 and Route 71 in Wallingford, Connecticut. Built in 1838 for the Hartford and New Haven Railroad by William MacKenzie, it is reported to be the first underpass in America.[1] The arch was designed to allowed tall hay wagons to pass through but it is not wide enough for modern two-way traffic, the one-way traffic being controlled by a pair of lights. Due to the age of the bridge, it has to undergo repairs on a regular basis References1. ^{{cite web|url = http://www.town.wallingford.ct.us/Content/Points_of_Interest.asp|title = Wallingford Connecticut: Points of Interest|publisher = Town of Wallingford|year = 2008|accessdate = 11 March 2011}} {{coord|41.4977|-72.8144|display=title}}{{Connecticut-bridge-struct-stub}} 4 : Buildings and structures in Wallingford, Connecticut|Tourist attractions in New Haven County, Connecticut|Bridges in New Haven County, Connecticut|Arch bridges in the United States |
