Traffic delays are expected to continue on Highway 10 over the coming weeks as crews work to repair the Ladner Trunk Road overpass after an over-height truck slammed into it on Tuesday afternoon.

The eastbound lane of the overpass, which crosses over Highway 99 south of the Massey tunnel, has been reopened, but the westbound lane remains closed and traffic must alternate using a single lane.

Thomas Chunn, with the B.C. Ministry of Transportation, says that despite the impact causing chunks of concrete to fall to the highway below, the overpass is structurally sound.

“Our engineers have done a preliminary assessment and they have determined that it is safe for us to run a single lane, alternating on top of Ladner Trunk Road,” he says.

Repairs are expected to take at least two weeks, but it’s unclear what the final cost will be.

According to RCMP, the driver had carried a similar load under the 4.6 metre high overpass earlier in the day, but misjudged the height of the second load.

The company responsible for the truck, BestLink Transport, declined to comment to CBC News on Wednesday, but the driver was fined $115 for the over-height load and $130 for improper trip logs.

The impact dislodged several large chunks of concrete, and although nobody was injured, RCMP Traffic Services says it could have been much worse.

“There were two vehicles that sustained cosmetic damage. If the concrete would have gone through a windshield, there was potential for high-risk damage,” said Cpl. Robert McDonald.

Inspectors from the Commercial Vehicle Safety and Enforcement unit are currently examining the truck.
