Local bridges are at the center of conversation after another snowfall in metro Vancouver.
Authorities are better prepared however and are closely monitoring the Alex Fraser and the Port Mann Bridges.
Bridge crews will reportedly be on site to ensure safe travel during winter conditions.
According to the Ministry, crews will perform precautionary safety measures as necessary. This includes spraying de-icing agent on the cross-beams of the Alex Fraser, and snow-clearing cable drops on the Port Mann.
This may lead to single-lane closures on the Port Mann for crew safety while they work.
Helicopter On Stand-by
The ministry has also arranged to have a helicopter on stand-by.
If snow and ice accumulates on the Alex Fraser and engineers determine there is a risk to public safety, the ministry will deploy the helicopter, which would result in a temporary bridge closure for 2-3 hours. If deployed, the rotors would create strong gusts of wind to blast the snow accumulations off the cables.
Also, if snow accumulations occur on the cables of the Alex Fraser, the ministry will continue tests of the cable-collar drop system. The testing will only require single-lane closures, and work will be done on Friday night from 10 pm to 4 am, so the impact to traffic will be minimal.
This testing has already been going on this week, as a ‘dry test run’ of the cable-collar drop system. If snow accumulations occurs, this will test the feasibility of the system under winter weather conditions.
