The Highway 91/17 Upgrade Project is underway and is designed to improve travel safety, reliability and efficiency on Highway 91, Highway 17 and the Highway 91 Connector in Delta, BC.

Construction-related activities for this Project include utility relocations, pile drilling/driving activities, girder installations required for the construction of several bridges/overpasses, and the installation of overhead directional signage. Embankment work, building retaining walls, and general roadwork activities such as aggregate base, asphalt and barrier placement, line painting and other activities are also underway.  

Construction activities will take place during the day when feasible.  To ensure the safety of the travelling public, however, some work is required to take place at night when traffic volumes are lower. Road users are requested to please use caution while travelling in these areas, and obey road and construction signs, posted speed limits and traffic control personnel.   

The work plan is subject to change based on changing road and weather conditions and necessary changes to the Project construction schedule. Follow DriveBC for the latest traffic information.  

To note: Please be prepared for a nighttime full closure of Highway 91 in both directions (northbound and southbound) between 72 Avenue and the Highway 91 southbound offramp to Nordel Way. This closure is required to transport bridge girders for the future interchange of Highway 91 and Nordel Way. 

• Work is anticipated to take place in spring 2022.  

• More detail on the work schedule and detour routes will be provided once available. 

Please be advised of the following activities in these key locations:

Highway 91C/Highway 17
