The British Columbia Ministry of Transportation and Transit needed to replace the existing George Massey Tunnel crossing. At 60 years old, the crossing didn’t meet current highway design or seismic standards for carrying Highway 99 under the Fraser River.
The Ministry hired the COWI-Stantec team to provide feasibility-level technical services and conceptual-level design to define the technical elements of different bridge and tunnel crossing options, as well as improvements to the approaches on Highway 99. Our team provided concept level designs and shortlisted three crossing concepts from 18 potential options. The design dealt with complex, interconnected traffic operations, geometrics constrained by available right of way, freeway ramps and ramp head intersections, poor geotechnical conditions, and environmentally sensitive areas. There were also drainage and constructability challenges within a high traffic corridor and a high degree of scrutiny.
Located between the communities of Delta and Richmond, this primary highway is a major north-south connector and a key goods movement route. Our designs and concepts helped the Ministry replace the aging bridge and improve safety for travelers with better protection against potential seismic events.
