#28 Rail Road Bridge Over Highway

Description:  Seen here is a railroad bridge that crosses a busy highway in Muskegon, Michigan.  Although seldom thought about by the general public, without bridges like this one the transportation infrastructure that makes up American would be much less efficient. This rather simple two span, steel bridge is designed to carry hundreds of tons in rail cars and allows both avenues for traffic to continue without interruption.  Image having to stop at an intersection like this one for a train while driving 70 MPH on the freeway!
