Winter Safety on Alex Fraser and Port Mann Bridges Explained

Rope Access Technician on Port Mann Bridge

Winter doesn’t mess with the Lower Mainland all too often. But when it does, our maintenance efforts go beyond the standard plowing and sanding of highways. Our attention is also drawn skyward to the cables on the Alex Fraser Bridge and Port Mann Bridge. Snow and ice can build up around the cables that support the bridges, becoming a safety hazard to traffic below if left to freeze, melt and potentially fall. To combat the risk, we developed cable...

Why Pile Driving is a Powerful First Step for Massey Bridge

If you’ve driven north on Highway 99 towards the George Massey Tunnel lately, you may have noticed a crane working on Deas Island. Crews were collecting geotechnical data as part of the George Massey Tunnel Replacement Project. The crane was equipped with a large pile driver, which pounded five piles into the ground to determine the maximum load a single pile can hold in that particular soil. The information will be provided to designers bidding on the contract to...

Why Moving a Bridge is a Shift in the Right Direction

Sometimes moving to something new means moving something older – but not too far. That’s the case with the single-lane Fort Nelson River Bridge, which we moved about 10.5 metres in mid-April, to allow for a new two-lane bridge to be built on Highway 77, about 70 km north of Fort Nelson. The existing bridge will serve as a detour while the new bridge is being built. This video shows the existing bridge – a lengthy 430 metres –...

Solving the Lions Gate Bridge “Bump” for Repairs

Lions Gate Bridge travellers may have had a bumpy ride during last year’s rehabilitation work that required us to use a temporary road plate while replacing a bridge deck joint. It’s time again to do some more rehab work; but please don’t worry – we have a smooth solution. In order to avoid traffic delays like the ones that happened last year, we’ve developed a comprehensive “bump-free” plan to keep traffic moving smoothly while we replace the expansion joint...

The Old Kootenay River Channel Bridge

The Old Kootenay River Channel Bridge

The Old Kootenay River Channel Bridge, or Old Kootenay Bridge as it is commonly referred to, is just west of Creston on Highway 3. If you’ve never been there before, you can see it here on Google Maps. It’s a straight, two-lane bridge about 300 metres long and runs over the Creston Valley Wildlife Management Area – a very sensitive wetlands ecosystem that’s home to a large number of hooved animals, lizards, amphibians and water birds. Like any bridge,...

From the Island to the Mainland – A Straight-Up Story About Bridging

From the Island to the Mainland – A Straight-Up Story About Bridging

It’s been raised many times in the past, and it’ll likely continue to be a hot topic as long as Vancouver Island remains separated from the mainland (which will probably be a very long time). We’re talking, of course, about building a connection across the Georgia Straight. The fixed link has been a fixation for us, Islanders and island visitors for decades. Common suggestions include building a bridge, like Prince Edward Island’s Confederation Bridge, or even a tunnel like...

Spring Cleaning: Why Wash a Bridge?

spring maintenance bridge

Just as people regularly maintain their vehicles, to extend their vehicle’s life, the ministry looks after its bridges to ensure they perform safely, for as long as possible. Over the winter, bridges get dirty from the sand, gravel and anti-icing chemicals that are spread on icy roads. So, when spring comes, it’s time for annual bridge cleaning. As with vehicles, the longer dust and road salt sit on painted bridge metal, the more it wears and fades paint. Even...
