Last week's answer

Question: The Linn Cove Viaduct in North Carolina is an engineering masterpiece that "hugs" Grandfather Mountain. Because the bridge constantly curves, climbs and tilts to follow the terrain, how many of its 153 massive pre-cast segments are exactly the same shape?

Answer: Zero (every single segment is a unique, custom-cast shape)

To maintain the integrity of Grandfather Mountain, the Linn Cove Viaduct is constructed with 153 unique pre-cast segments, all mostly utilizing  a curved shape to wrap around the mountain. Only one segment at its southernmost part is completely straight.
