This design was my favorite, but it also met all the requirements provided. The overall span is 190 feet with a space to allow a 30 feet x 40 feet object to pass through. The height of the bridge is 90 feet tall and 12 feet wide. The section that opens works on a gear system. When the gears turn it retracts the cables making the side supports pull away from the road deck. Then the road deck is lifted by cables so the object can pass through.
