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 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, 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, requiring us to build a new highway alignment and a new bridge across Cache Creek. We will be building an embankment on the easternmost portion of this segment.

Current activities
  • Construction of a 590-metre-long bridge and six-kilometre highway grade at Cache Creek continues.
  • The contractor will continue the construction of the highway grade, which includes removal of unsuitable material, placement of geotextile fabric and hauling and placement of aggregate from the Peaceview Pit to the future highway alignment.
  • The contractor continues to install bridge foundations, which includes the installation of concrete piles and the construction of concrete bridge piers. Bridge pier construction includes the installation of steel rebar, formwork and the placement of concrete in multiple lifts.
  • Aggregates will be hauled from Peaceview Borrow, Portage Mountain and West Pine quarries.

Segment length: 4 km
Construction: 2018 to 2021

Construction of Cache Creek West began in 2018. This four-kilometre segment of highway west of the Cache Creek Bridge will be realigned to prepare for reservoir filling in September 2023.

Current activities
  • Construction is complete.

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 segment includes design and construction of 1.5 km of new highway and a 158-metre-long bridge.

Current activities
  • Construction of a 192-metre-long bridge and 1.5-kilometre highway realignment at Dry Creek is in progress.
  • Current activities include drilling bedrock and installing rock anchors and constructing concrete bridge foundations. Concrete bridge foundation construction includes installation of rebar, formwork and the placement of concrete in multiple lifts.
  • The contractor will continue grubbing, stripping and removal of unsuitable material from the future highway alignment. Aggregates will be hauled from borrow sites and stockpiles and placed on the highway embankment.

Segment length: 2 km
Construction: late 2020 to 2023

This 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.

Current activities
  • Construction of a 411-metre-long bridge and 1.9-kilometre highway realignment at Farrell Creek continues.
  • Concrete bridge pier and bridge abutment foundation construction will continue including the installation of rebar, formwork and pouring of concrete.
  • The contractor will continue construction of the highway alignment and tie-ins including removal of unsuitable material, placement of geotextile fabric and placement of aggregates hauled from on-site borrow sources.
  • The contractor will continue crushing aggregates on site.
Future activities
  • Road construction, including grading, paving and bridge construction

Segment length: 3 km
Construction: early 2021 to 2023

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.

Current activities
  • Construction of a 3.5 kilometre highway realignment at Farrell Creek East continues.
  • The contractor will continue construction of the highway alignment which includes removal of unsuitable material, placement of geotextile fabric and placement of aggregates hauled from on site borrow areas.
  • The installation of fencing will continue.
  • The contractor will operate a processing plant to produce aggregates.

Segment length: 4 km
Construction: 2018 to 2023

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.

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 1.42-kilometre-long bridge and a three-kilometre highway realignment at Halfway River continues.
  • The installation of a cast-in-place bridge deck and parapets is in progress. This includes the installation of scaffolding, formwork and rebar on top of the bridge steel girders and pre-cast deck panels. Concrete will be placed in multiple lifts and work may occur 24 hours a day during the placement and curing of concrete.
  • Bridge abutment construction is in progress, which includes installation of formwork, rebar and concrete, as well as placement of bridge end-fill aggregates.
  • Grading will continue on the new highway alignment and will include the placement and compaction of aggregate on the highway embankment. Aggregates may be hauled from Portage Mountain Quarry.

Segment length: 8 km
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.

Current activities
  • Construction of a 150-metre-long bridge and 8.5-kilometre highway realignment at Lynx Creek is in progress.
  • A short section of distribution poles are being relocated temporarily due to the temporary realignment of the road.
  • The contractor will continue construction of the highway alignment including removal of unsuitable material, placement of geotextile fabric and placement of aggregates hauled from Gates Island and borrow sources within the work site. Overburden removal and gravel extraction at Gates Island will continue to support embankment construction.
  • The construction of bridge foundations will continue, including the installation of piles for the bridge foundations and concrete foundations for bridge piers and abutments. Piling includes drilling into bedrock, installing steel pile casings and rebar and pouring concrete. Foundation work includes installation of rebar, formwork and the placement of concrete in multiple lifts.
  • A traffic detour at the east end of the work site will begin construction, including grading, roller compacting and then paving. The detour is expected to be in place for traffic at the end of June or early July.
  • Hauling of rock from Portage Mountain Quarry may occur.
