We're committed to providing Peace region residents, businesses, communities and Aboriginal groups with information about Site C construction activities in a timely manner.

Please sign up for construction updates to make sure you are receiving up-to-date information about the Site C project.

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 B.C..

When reservoir filling begins as early as fall 2023, the Site C reservoir will widen the Peace River by two-to-three times, covering parts of the highway.

We are partnering with the Ministry of Transportation and Infrastructure to realign segments of Highway 29. Construction started in 2018 and will continue until mid-2023.

The work involves designing and building approximately 30 km of highway, including new bridges at Cache Creek, Halfway River, Lynx Creek, Dry 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
Construction: 2019 to 2023

At Cache Creek East, the new reservoir will cover the existing highway. We’re building a new highway alignment and new Cache Creek Bridge, which opened in December 2022. We’ll also build an embankment on the easternmost portion of this segment.

Current activities
  • Construction of a 596-metre-long bridge and six-kilometre highway section at Cache Creek continues.
  • Construction of the highway is in progress, including asphalt paving.

Segment length: 1.5 km
Construction: late 2020 to 2022

A segment of Highway 29 at Dry Creek will be covered by the new reservoir. The new alignment for this section includes a 1.5-kilometre-long highway realignment, and the design and construction of 158-metre-long bridge, which opened in September 2022.

Current activities
  • Decommissioning work, including the removal of the asphalt, signs, and concrete barriers.

Segment length: 2 km
Construction: late 2020 to 2023

The original segment of highway at Farrell Creek will be covered by the new reservoir. The new alignment involves construction of a new bridge across Farrell Creek, which opened to traffic in October 2022.

Current activities
  • Construction of a 1.9-kilometre highway realignment at Farrell Creek continues.
  • Single lane alternating traffic will be required periodically.
Future activities
  • Road construction, including grading, paving, and bridge construction

Segment length: 3 km
Construction: early 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. So, we’re relocating the highway north, outside of the impacted area.

Current activities
  • Construction of a 3.5-kilometre-long highway realignment at Farrell Creek East continues.
  • Traffic has been moved onto the new highway alignment.
  • Construction will pause for the winter and resume next spring.

Segment length: 4 km
Construction: 2018 to 2023

In the Halfway River area, the reservoir will cover the existing highway and bridge, requiring re-alignment of Highway 29 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.

The Ministry of Transportation and Infrastructure has awarded the contract for construction of this segment to Eiffage-Infracon Halfway River Joint Venture (Note: This joint venture is not affiliated with Halfway River First Nations).

Current activities
  • Construction of a 1.05-kilometre-long bridge and a three-kilometre highway realignment at Halfway River is complete and the bridge is expected to open to traffic in early 2023.
