Michigan's Bridges: West Maple Road Golf Course Bridge

August 2003 (42.545 Degrees, -83.277 Degrees) West Maple Road Arch Bridge
I had to ask my brother for help identifying this last bridge photo from Michigan. He reminded me that it's the bridge that carries golf carts across West Maple Road from one side to the other of Oakland Hills Golf Course. It looks like a two pinned arch supporting long girders from 'V' shaped hangers. I like the 'modern' parabolic shape of the arch.

Michigan's Bridges: Tamarack Way Arch Bridge at Cranbrook School

August 2003 (42.575 Degrees, -83.245 Degrees) Tamarack Way Bridge
Just downstream from the Trellis Bridge is a closed spandrel arch bridge designed in the slightly wide and flattened style of Frank Lloyd Wright. This little bridge has four horizontal indentations near the base, little squares (formwork bolts?) along the top, four horizontal rails above the concrete barriers, and squat pedestals on the deck. It's a nice, clean design, with the minimum of decoration to give a modern, classical look. I don't know anything about who designed it, but it certainly is in the Cranbrook architectural style.

Michigan's Bridges: Trellis Bridge at Cranbrook School (2)

August 2003 (42.575 Degrees, -83.245 Degrees) Trellis Bridge
A closer look at the Trellis Bridge at Cranbrook Academy. We can see how steel 'X' braces are bolted to the bottom and top timber elements to support the bowed trellis members. The trellis serves no structural purpose other than to support a timber beam above the bridge deck. It's like a covered bridge, only less covered. I would like the bridge more if the various elements had a purpose (at least by supporting some ivy or roses).
