The BC Ministry of Transportation & Infrastructure retained Klohn Crippen Berger for preliminary and detailed design of a new railway overhead at 41B Street and Deltaport Way.
The new overhead replaces an existing at-grade crossing of the CN Rail tracks. A new loop ramp and signalized intersection provide access from 41B Street to Deltaport Way. A two-span (73 m – 78 m) continuous steel girder bridge with a composite concrete deck was designed to span over Deltaport Way and the CN Rail tracks. The bridge carries two lanes of traffic and a sidewalk.
A detour for 41B Street was developed through the construction zone over the railway to allow for construction of the bridge on the original 41B Street alignment. Traffic planning and staging were extremely complex and was a key part of the project success.
