Michigan's Bridges: 27 Mile Road Overcrossing in Calhoun County

August 2011 (42.268 Degrees, -84.776 Degrees) 27 Mile Road Overcrossing

The next bridge is another four span haunched girder bridge, but at a 45 degree skew to the expressway below. This has the effect of making the superstructure longer and deeper. The 27 Mile Road Bridge is 360 ft long instead of the 227 ft length of yesterday's perpendicular bridge. It's because the expressway (which connects Chicago to Detroit) takes a diagonal jog to the right while 27 Mile Road continues its north-south direction (like all the other mile roads).

I like the deeper girders and the better view of the piers that the skew provides.
