An advisory about traffic restrictions in Langley was issued after a second sinkhole was discovered near a Trans Mountain pipeline work site.

Langley Township Councillor Rob Rindt said when the first sinkhole was discovered a few weeks ago, on 240th Street, between 80th and 72nd Avenues, across from his family farm, a representative of Trans Mountain told him it was a 含羞草研究社渙ne-off,含羞草研究社� assuring him that he didn含羞草研究社檛 have to worry about.

Then, a second sinkhole was discovered on the other side, 含羞草研究社渙n my property,含羞草研究社� Rindt said.

An advisory posted to the Township website on Sunday morning, May 14, said due to 含羞草研究社渁 road surface failure, 240th Street will be reduced to single-lane, alternating traffic with short duration closures between 80th and 72nd Avenues.含羞草研究社�

Traffic control personnel were on site, and traffic lights with motorized flags were being used to control traffic movement.

In response to a Langley Advance Times query, a statement from a Trans Mountain spokesperson on Monday, May 15, confirmed there have been two sinkholes associated with the construction of their pipeline through Langley.

含羞草研究社淭renchless construction is occurring on 240th Street for the Trans Mountain Expansion Project,含羞草研究社� the statement said.

含羞草研究社淭here is currently a horizontal directional drill (HDD) underway, which is a method to safely cross underneath watercourse crossings, railways, highways, sensitive environmental areas and in places with restricted workspaces, such as urban areas.含羞草研究社�

In April, there was what Trans Mountain described as 含羞草研究社渃hallenging ground conditions in the area where a localized sinkhole formed.含羞草研究社�

Crews were able to fix the sinkhole temporarily and installed a road plate, and for the 含羞草研究社渟afety of the public and crews, the team determined the need for further stabilization and installed a single lane alternating traffic pattern to complete the trenchless crossing.含羞草研究社�

When the localized sinkhole reappeared over the weekend, crews temporarily redirected traffic, Trans Mountain said.

含羞草研究社淥nce the trenchless crossing is complete, the sinkhole will be permanently repaired, and the road will be returned to the same condition it was before construction started.含羞草研究社�

Work on the trenchless crossing was expected to wrap up at the beginning of next week.

Once complete, the pipeline, running through Langley and other areas of the Lower Mainland, will triple the amount of oil products shipped from Northern Alberta to a refinery and terminal in Burnaby.
