Completed last year, the High Trestle Trail Bridge in Boone County, Iowa was designed by public artist David B. Dahlquist of RDG Dahlquist Art Studio in response to a “call for artist” competition issued by the Iowa Natural Heritage Foundation. Purely sculptural, as opposed to functional or a structural part of the bridge, the final design has a blooming quality, or maybe camera-shutter-like effect, head on. Surprisingly, from the side, one can appreciate how spaced out the individual steel archways actually are. It’s interesting to see the lit-up nighttime version which has such a different, more futuristic look. Either way, I’d say it’s a very successful and striking design.
If you like this bridge you might also enjoy the Twist Bridge.
