Klohn Crippen Berger Ltd. was retained by the British Columbia Ministry of Transportation to provide complete design services for the Annacis Channel West Bridge. This reinforced concrete structure is comprised of a 300 m long main span with two elevated approaches on the north side. The superstructure incorporates pre-cast, pre-tensioned concrete girders made continuous over the river spans via staged post-tensioned construction. The deck is designed to be continuous for 300 m between expansion joints to reduce maintenance and improve seismic performance. The majority of the structure is founded on 914 mm diameter steel pipe piles driven to approximately 70 m depth. These piles were designed as friction piles and will permit a stable rocking foundation response under seismic loading. Construction of this structure was completed in August of 1997.
