#47 Bridge Week!: Steel Arch with Hanger Cables Bridge

Description:  This is the I-94, Telegraph Road Bridge near Detroit, Michigan.  This seemly out of place bridge is needed to span over Telegraph road to allow for unobstructed traffic flow beneath I-94.  It uses a combination of steel arches and tension cables to carry the load of the deck and passing traffic.  The road deck takes load to the cables, which are hung from the steel arches.  These steel arches then complete the load path by bringing the load to the ground.  If you look on the right side of the picture, the top of the foundation of the bridge can be seen where the blue arch contacts the ground.

  2. This bridge is really impressive. It was actually built before Super Bowl XL in 2006 in Detroit, so the visiting fans would see this bridge on the way from DTW to Ford Field. When you're driving on I-94, it's supposed to look like a football in front of you.
