context_page_description: The Sunniberg Bridge is a curved multi-span extradosed road bridge with low outward-flaring pylons above the roadway edges, designed by Christian Menn and completed 1998. It carries the Klosters bypass road 28 across the Landquart River near the village of Klosters in the canton of Grisons in eastern Switzerland. It is notable because of its innovative design and aesthetically pleasing appearance sensitive to its surroundings.
context_section_description: Construction started Spring 1996, by Batigroup AG and Vetsch AG, starting at the north end with pier P1, the pier closest to the Landquart to Klosters road. Once the piers were completed, the deck were erected using the balanced cantilever method. The bridge was completed ahead of schedule in Fall 1998.
  The completed bridge was not opened for traffic because the Gotschna Tunnel, to which the south end of the bridge was connected, was still under construction. Instead, it was used only to access the excavation sites for the tunnel in the interim, until 2005 when the Klosters bypass, including both the bridge and the tunnel, was opened for traffic in a ceremony with Prince Charles, a frequent visitor to Klosters.
