Wooden overpass with 17-meter span arch construction between concrete walls. This project provides a safe crossing for wild animals like deer and wild boars over the A1 motorway. 156 curved Switzerland spruce beams, constructed off-site through individual lamination, pressure-impregnated, glued and then bent to create the curve form of the tunnel-like interior. Each of the beams were placed individually, which took approximately 15 minutes each, and then a secondary glulam limber structure was placed and finished with a laminated veneer lumber sealant layer. The bridge was then covered with earth and planned to blend with the surrounding forest environment.
