Old Town Bridge (Norwegian: Gamle Bybro or Bybroa) is located in Trondheim, Trøndelag County, Norway.
[1] Gamle Bybro crosses the Nidelva River from the south end of the main street Kjøpmannsgata connecting to the Trondheim neighborhood of Bakklandet.
[2] Gamle Bybro was constructed by Johan Caspar von Cicignon in 1681 in conjunction with the reconstruction of Trondheim after the great fire of 1681.
Gamle Bybro is also known as Lykkens portal (Gate of Happiness), after the lyrics of the popular waltz Nidelven stille og vakker du er ( "Nidelven quiet and beautiful you are") by Norwegian singer and composer Kristian Oskar Hoddø (1916-1943).
According to tradition, Hoddø wrote the waltz about the Nidelva River one night in late April 1940 while he was standing at Gamle Bybro.
