Michigan's Bridges: West Michigan Avenue Overcrossing in Jackson County

August 2011 (42.266 Degrees, -84.620 Degrees) West Michigan Avenue Overcrossing
This is my last photo of a four span bridge across I-94. It seems like they could have gotten away with a two span over crossing but they apparently wanted very gentle embankment slopes, which pushed the abutments too far apart. It looks like there are two 70 ft long center spans and two 35 ft long end spans. The concrete looks more blue than at the previous bridges, perhaps because it was mixed at a different plant. Also, the vertical clearance is very low. I thought 16.5 ft was the minimum vertical clearance over the Interstate. I'm surprised the bridge hasn't been hit.
