Highway 29
Connecting the community of Hudson's Hope with the Alaska Highway and Fort St. John, Highway 29 winds along the north side of the Peace River in northeastern British Columbia.
When reservoir filling begins in September 2023, the Site C reservoir will widen the Peace River by two-to-three times, covering parts of the highway.
As a result, BC Hydro is partnering with the Ministry of Transportation and Infrastructure to realign six segments of Highway 29. Construction started in 2018 and will continue until mid-2023.
The work involves designing and building 32 km of highway, including new bridges at Cache Creek, Halfway River, Lynx Creek and Farrell Creek.
Realigning each segment involves:
- Geotechnical, environmental, and archeological studies
- Improved highway alignments, including grading, paving and bridge construction
- Geotechnical stabilization works
- Moving electrical and phone lines to accommodate new highway construction
- Decommissioning the existing highway after construction
During construction, the highway will remain open to ensure efficient movement through the construction sites.
Some minor delays should be expected, and drivers should slow down and obey all traffic control personnel and signage. Get the latest traffic updates at drivebc.ca.

Segment length: 6 km
Site preparation: 2018 to 2020
Construction: 2020 to 2023
At Cache Creek East, the new reservoir will cover the existing highway, requiring us to build a new highway alignment and a new bridge across Cache Creek.
We will begin work on Cache Creek East in fall 2019 by building an embankment on the easternmost portion of the segment.
Completed activities
- Geotechnical investigations

Construction: 2021 to 2022
While the existing stretch of Highway 29 east of Farrell Creek will not be covered by the new reservoir, it may be more prone to erosion. For this reason, we are relocating the highway north, outside of the impacted area.

Segment length: 4 km
Site preparation: 2019
Construction: 2019 to 2022
We began preparing for construction of the realignment at Halfway River in early 2019. In this area, the reservoir will cover the existing highway and bridge, requiring re-alignment of the highway and construction of a new bridge. This new segment of highway will be three kilometres long, and the new bridge will be one kilometre long.

Segment length: 8 km
Site preparation: 2019 to 2021
Construction: 2019 to 2023
As the longest segment of highway to be realigned, it will take four years to construct the Lynx Creek segment. These eight kilometres of highway include a new bridge, causeway, and embankment. Construction of the embankment will start in fall 2019.
