At $98 million, the Highway 1 Keith Road / Mt Seymour Parkway Interchange was one of the largest and most complex design-bid-build projects the BC Ministry of Transportation and Infrastructure (MoTI) has undertaken and required innovative solutions to reduce traffic congestion, improve safety, and enhance active transportation, while meeting tight completion and funding deadlines. Part of the larger $198 million Lower Lynn Improvement Program, the project was designed to reduce public frustration over one of British Columbia’s most congested sections of highway.
McElhanney had to overcome the challenge of working within a constrained, sub-urban, congested corridor that included fish-bearing creeks, sensitive habitat, parks, residences, and commercial properties. Additionally, understanding that this project was under intense public scrutiny and a highly constrained schedule tied to funding, McElhanney accelerated the design schedule from 15 months down to six months. The time saved to complete the design provided MoTI with an additional construction season to ensure that the project was completed on time.
“Not only was McElhanney instrumental in the development of this project but they can take pride for getting it to construction within budget and on time. The team went over and beyond to ensure the ministry’s vision and objectives were achieved.”
— Jay Porter, MoTI Senior Project Manager
This project promoted sustainability through reduced travel time and congestion, improved transit infrastructure and access, and enhanced active transportation options including multi-use paths and a pedestrian tunnel. The final design also featured sound walls incorporating artwork from local Indigenous artists to create a unique finished product.
