Construction of second Wapiti River bridge begins as part of Highway 40 twinning

July 19, 2021  By Rock to Road Staff

Construction of the second bridge over the Wapiti River was set to begin today on Highway 40 in Alberta.

It is part of the twinning of Highway 40, a $106 million project on the roadway running south of Grande Prairie, Alta.

The province warned motorists to expect delays on Highway 40 at the intersection of Township Road 700 as a result of the construction. The bridge construction will result in a partial closure of access to and from Highway 666.

Traffic impacts

  • There will be no access for traffic to enter Highway 40 northbound/southbound from Highway 666.
  • Motorists will detour to Township Road 700 to access Highway 40 northbound/southbound.
  • There will be no access for traffic to enter Highway 666 westbound from Highway 40 northbound.
  • Motorists will detour to Township Road 700 from Highway 40 northbound.
  • Reduced speeds will be in place and temporary four-way traffic signals will be installed at the intersection of Highway 40 and Township Road 700.
  • Southbound traffic on Highway 40 will be able to use the exit south of the Wapiti River bridge to access Highway 666 westbound.

The detour and temporary traffic signals are expected to be in place until late fall.


Motorists are asked to be patient, obey signage and travel safely through the construction zone.
