Vebjørn Sand Engineers da Vinci Bridge in Ås, Norway

Vebjørn Sand, a contemporary Norwegian artist, became interested in da Vinci’s designs for a self-supporting arched bridge in 1996. Through a partnership with the Norwegian Public Roads Administration (NPRA), Sand was able to build a da Vinci bridge for pedestrians and bikers crossing Highway E18  in the municipality of Ås, Norway. This was possible only because of the NPRA’s historic receptiveness to projects that combine art with functionality in public space. The design is slightly modified; while da Vinci’s original design only had one parabola, the bridge in Ås is supported by three parabolic arches. The parabolic structures are suited to this design by distributing weight to the wide metal pillar abutments at the base. The bridge is made of laminated wood reinforced with steel, rather than the stone that da Vinci had originally proposed. Construction of the 330 foot long bridge by the Moelven Group lasted approximately 5 years, from 1996 to 2001. The bridge was opened to the public in November of 2001 by Queen Sonja of Norway.
