When I was a kid there was a sign in an Oklahoma restaurant that said,
"The shortest distance between any two points in Oklahoma, is under construction."

I've crossed a bridge or two I'm my life, if that's what you want to believe.I agree that they aren't fun to drive but you should be thankful they are that way. The arc in the spans are called camber which put simply means it has a preloaded stress/arc above plane. If there were to be a traffic jam and the bridges were backed up, the spans are engineered to handle the weight of all those cars. At that load rate the span should be almost flat with no discernable arc when fully loaded. If they started out with no/light load at no discernable arc, when capacity was reached it would result in a bow (arc below plane) which would certainly result in catastrophic failure.

Negative. The camber deflection is designed to sit flat once the deck load is applied. These beams are indeed pre-stressed but this was a definite screw up by the designer. These bridges are in fact designed to be able to hold bumper to bumper semi trucks as well as one over loaded rig like a crane. But they are supposed to be flat and not arced. There is another one like this on the new turnpike north of Yukon.I've crossed a bridge or two I'm my life, if that's what you want to believe.
Who cares, its a toll road so your not paying for it unless you use it.Does anyone know why they are widening a road(creek tpke) that's only six or so years old and has NO traffic problem ??????
Makes no sense.
