Although I can't remember how long ago, when the second span across the the Mississippi at New Orleans reached the center (begun from both sides) there was a seven foot misalignment at the top. It was allegedly due to temperature differences during construction. My question is/was how did the builders of the first companion span get it right?
 
Did others get it wrong too? If not sloopy enginering.
