Coquihalla and Yellowhead County construction updates

Coquihalla

District of Hope – Old Hope Princeton Highway Coquihalla river crossing

• *Work at this site is currently underway.
• This work will use diversion pumps to reduce the water flow around the excavation area. Heavy equipment will be used instream to prepare the trench within the Coquihalla Riverbed with water monitoring taking place throughout the construction process. The pipe will be installed using conventional construction. After the pipes are installed, the stream will be returned to the natural flow path and the site will be reclaimed to its original condition with additional bed and bank flood protection.
• At the same time, Trans Mountain is replacing a segment of the existing pipeline. Both installations will happen simultaneously and alongside each other to limit environmental impact on the Coquihalla River and to minimise disruptions to residents.

• *Work at this site is currently underway.
• Stream isolation will be used to cross under the Coquihalla River south of the Coquihalla Highway exit 192. In this type of construction, the waterway is temporarily dammed and rerouted with pumps or piping. The pipe is then installed using conventional construction techniques before the dam is removed and the stream is returned to its normal flow path. The site will be reclaimed to its original condition with additional bed and bank flood protection.
