This is true and still exists: The Huey P. Long Bridge in Bridge City, La was built from each side into the middle instead of one side all the way across. The surveyors miscalculated so that the two sides did not meet exactly plumb. On the East side of the bridge there is a notable but small curve. I used to have to drive it every day for several years and I laughed every time I got to that part of the bridge! On the way home I laughed when I got to the slight curve when travelling in the other direction! ;-)
It probably can be seen in photos or videos.
Back in college we called it “Close enough for tunnel work”. The guy that surveyed for the Eisenhower Tunnel outside of Denver was a professor there. He was off by something like a foot when he surveyed for the tunnel.
But - the survey was for a 10-foot diameter initial tunnel (coming in from both the west and the east and meeting in the middle). The error was easily smoothed out when building the much larger, multi-laned freeway tunnel that is over a mile long.
