The first bridge was completed in 1935. The second was completed in 1960. They must have used the original designs for the second bridge because they are nearly identical.

It's difficult to see at this resolution, but the bridge on the right appears to have an aerodynamic concrete deck. Other than the shape of the concrete, I didn't notice any other differences despite the 25 year difference in age.
