Just throwing this out there, but the bridge should have been salted/sanded at the very least. As far as I know it wasn't. If the bridge ices easily, as it apparently does, there needs to be some sort of plan to de-ice on cold days.
Drivers here are terrible, as everyone knows. Even so, 40 car accidents aren't normal.
As was noted the de-icing solution was applied the day before (Wednesday 4am) and it was supposed to be effective for 48 hours - it was not.
Transportation Investment Corporation spokesman Max Logan told CTV News the contractor hired to monitor the Port Mann hadn’t doused the bridge with de-icing solution since 4 a.m. Wednesday.
“The amount that they put on they thought was sufficient for a 48 hour period, it obviously was not,” Logan said.
The service provider, Mainroad Contracting, also patrolled the billion-dollar toll bridge six times between 10 p.m. Wednesday and 5 a.m. Thursday, but saw no sign of ice danger.
“Ice did accumulate very rapidly between 5 and 6,” Logan said. “We have said to them that from now on application of that de-icing solution every 48 hours is not sufficient. It needs to happen more frequently, at least once a day when we have conditions like tonight and yesterday.”
Logan said sand is generally not used on roads in the Lower Mainland, but that salt could be laid in addition to the de-icing solution, which consists of a brine-saltwater mix.
