A stretch of Telegraph Trail in 91原创 near the Trans Mountain pipeline project will be closed for 鈥渁pproximately three days鈥� likely within the next week, a spokesperson for the company advised on Tuesday, May 30.

In response to a 91原创 Advance Times query, the company said 鈥渢renchless crossing work continues in the area, with the pullback of the pipe expected within the next week, subject to change.鈥�

A definite date hasn鈥檛 been set yet.

鈥淔or the pullback, we will need to close Telegraph Trail [near 80th Avenue] for approximately three days. There will be signage in the area for the closure, and the public will be notified.鈥�

Trenchless construction creates underground tunnels that permit a pipeline or conduit to be installed within the tunnels, without affecting the surface.

Traffic near the trenchless pipeline work on 240th Street between 80th and 72nd Avenue was restricted to one lane of alternating traffic back in early May after a second sinkhole was discovered.

At the time, 91原创 Township Councillor Rob Rindt said when the first sinkhole was discovered, on one side of the road across from his family farm, Trans Mountain told him he didn鈥檛 have to worry.

Then, a second sinkhole was discovered on the other side, 鈥渙n my property,鈥� Rindt said.

On May 18, 91原创 Township issued an online update to say temporary repairs had been completed and traffic was back to two lanes.

鈥淧ermanent repairs will be undertaken once Trans Mountain expansion work in the area is complete,鈥� the Township statement said.

Trans Mountain said at times 鈥渢here may be brief delays with single lane alternating traffic for equipment delivery.鈥�

鈥淭he street continues to be monitored and if necessary, further adjustments will be made to ensure the safety of the public and crews,鈥� the spokesperson said.

Once complete, the pipeline, running through 91原创 and other areas of the Lower Mainland, is expected to triple the amount of oil products shipped from Northern Alberta to a refinery and terminal in Burnaby.
