This article outlines the process and challenges involved in designing and building a new structure to span the Uupaachikus Pass in Mistissini, Quebec. The 160- metre-long bridge was designed using semi-continuous arches made of glued laminated wood (glulam) girders. The bridge is 9.25 metres wide and has spans of 37, 43, 43 and 37 metres. The Glulam Bridge features straight girders with a maximum length of 24 metres attached to 15-metre arched girders by means of steel plate assemblies. The arches are connected to the piers and abutments using pins.
