Q. What is the road/highway service area that Mainroad South Island Contracting is responsible for maintaining?
A. The South Vancouver Island Service Area 1 is 3,615 lane kilometers of roadway from Chemainus in the North end to Victoria including roads to Port Renfrew, Lake Cowichan, Sooke and all of the roads on the six Southern Gulf Islands (Galiano, Mayne, Pender, Salt Spring, Thetis and Saturna). Mainroad is not responsible for plowing strata roads.
The service area includes the maintenance of 201 bridge structures and at last count, approximately 144,000 signs.
Q. Where are Mainroad’s maintenance yards located?
A. The headquarters and primary works yard for Mainroad South Island Contracting is in Langford with supporting works yards in:
- North Duncan
- Cobble Hill
- BC’s Gulf Islands | Galiano, Mayne, Pender, Salt Spring, Thetis, and Saturna.
Q. How many Mainroad employees are working during winter operations?
A. Our fleet and crews are fully engaged in winter maintenance operations. Over 80 employees plus mechanical support are available to work around the clock to keep our roads clear.
Q. Why are some roads plowed more than others? Which streets get plowing priority?
A. It’s important for everyone to know that Mainroad’s time is determined by the standards set by the Ministry of Transportation and Infrastructure. Priority is given to major highway routes such as numbered highways and school bus routes which are primarily used by emergency services and the majority of traffic. In emergency situations where police, fire, and ambulance are needing assistance, Mainroad crews will clear the road for first responders to get through. Other road frequency is determined by winter traffic volumes. These frequencies are reviewed annually by the Ministry to ensure that plowing priorities reflect any changes in the road network.
When winter hits, we need to keep service area roads as clear as possible. Sometimes when the snow is falling fast, it can build up quickly again right after the plow passes. In those cases, it’s not uncommon to see those higher-priority routes plowed several times before we can turn our attention to other areas with lower traffic volumes. It can be a real challenge to keep up with clearing the snow during a severe storm event but using the Ministry’s priority approach allows Mainroad to make the best use of resources to keep roads as safe and reliable as possible.
Clearing down trees and vegetation after other types of winter storms such as a wind storm can take some time for our crews to respond particularly if they encounter a down power line. In this case, crews will coordinate with BC Hydro to determine when the area is safe. If you see a tree within 3 metres of a power line, leave the tree alone and call BC Hydro at 1-800-224-9376. Avoid touching anything, such as a car, object or equipment, or anyone who is in contact with a fallen power line. Keep children and pets away from fallen electric lines. Avoid driving over a fallen power line. Call 911 immediately to report a fallen power line.

Q. What is Mainroad doing ahead of a winter storm event?
A. Mainroad crews will be patrolling service area highways and roads while monitoring the forecast closely. Crews will apply specific material to the road surface as determined by the forecast and actual weather conditions. Pre-storm activities typically include pre-salting/brining and monitoring the forecast closely. The proactive use of an anti-icing brine (for example) is a proven way of combatting ice from forming on the highway surface. This technique is used throughout most highway maintenance jurisdictions in North America. During a heavy rain advisory, crews will check and clear service area catch basins.
Ahead of a weather event, Mainroad releases regular road and weather updates to a contact list of local agencies, various stakeholders including the Ministry and Media to help inform the public. This helps everyone understand the current conditions, expected weather and Mainroad’s response. These updates are also posted on our social media.
When a weather event occurs, (snow, freezing rain, flooding, etc.) our entire fleet and crews will be fully engaged in winter maintenance operations. Up to 80 employees plus mechanical support are available to work around the clock plowing, sanding and/or salting as conditions warrant and patrolling the service area. Additional crews will be called into to plow the roads.
Q. What materials does Mainroad use for winter road maintenance and when are these materials applied?
A. Mainroad uses three materials for winter road maintenance: winter abrasive, anti-ice liquids and salt. The use of a specific material is determined by the forecast and actual weather conditions and in accordance with the standard set by the Ministry.
- Winter Sand: The winter sand used by Mainroad is a graded material specified by the Ministry of Transportation and Infrastructure.
- Anti-icing Brine: Anti-icing brine is used as a preventative material prior to snowfall. Typically, these materials are applied prior to a forecasted winter event and dry on the highway surface to provide early on snow melting capabilities.
- Salt: Salt is a staple of our winter maintenance routine. Sometimes salt is used in a liquid, sometimes in a solid. It helps to melt the ice, and then the slush can be plowed away. There’s a lot of science behind it, but there’s a real art to using salt as well. Using a fast-acting salt can work well when there isn’t much snow, for example. But if the snow keeps coming, the fast-acting option will create a lot of water, which will dilute the salt and make it less effective.
Salt is only effective in certain temperatures. If temperatures fall below -5C, salt becomes a lot more ineffective. Also, if the ice melts and then the temperature suddenly dips, it can actually make things worse, because that slush and melted water is just going to freeze again.
The use of a specific material is determined by forecast and actual weather conditions.
Q. How does Mainroad monitor weather and highways conditions?
A. As the weather can change rapidly on Vancouver Island, Mainroad is continuously monitoring weather and highway conditions. To determine how best to protect motorists, we oversee weather in two ways:
Northwest Weather Net: Mainroad hires the services of Northwest Weather Net, one of the world’s leading weather forecast providers, to monitor the area’s weather and provide several forecasts, each specific to local sub-area’s needs.
Road Patrols: 24 hours per day, 7 days per week our operators are on the road observing current conditions and making the calls as to what maintenance is required.
Environment Canada also contributes to our weather watch, providing regional forecasts. Combined with additional weather information from sources such as airports, these tools help us predict road conditions. But firsthand experience is also a big part of knowing our roads. That’s why Mainroad patrols the highways on a regular basis.
Road Weather Forecasting: Environment Canada’s Meteorological Service of Canada does not perform road weather forecasting. This vital service is only available through private sector service providers. The Ministry of Transportation and Infrastructure contracts with a leading road weather forecaster, which watches over B.C. weather 24 hours a day, seven days a week.
Q. Who ensures the work is being done properly?
A. There are two ways in which work is assessed against contractual commitments:
Mainroad has a vigorous quality assurance program in place, which tracks our own performance. Should areas of concern be detected, measures are put in place to deal with the shortcoming and processes are modified to prevent recurrence. Mainroad is an ISO compliant company and its quality programs are built on those models.
The Ministry of Transportation and Infrastructure has an ongoing inspection process that involves a high-level overview using resources from areas across the Province, as well as numerous detailed inspections that drill into the inside workings of Mainroad’s maintenance practices.
Q. Where can I direct concerns about road conditions to Mainroad South Island Contracting?
A. We encourage motorists, residents and cylcists to report all road condition concerns by phone to our 24-hour call centre number.

- Conditions change and so should your speed. Please SLOW DOWN and drive for the conditions.
- We encourage all motorists to drive to the conditions during the winter season, slow down, and increase the distance between yourself and the vehicle in front of you.
Snow Plow Safety Do's and Don'ts
…Turn on your head and tail lights during heavy snow or rain, even during the day.
…Use winter-rated snow tires with the mountain-snowflake symbol.
…Watch for the flashing amber lights. It can be difficult to see snow removal equipment.
…Give snow plows plenty of space – about 10 car lengths. Salt and winter abrasives, as well as rocks and other debris in the snow, can fly – hitting nearby vehicles and decreasing visibility.
…Remember the road surface ahead of the plow hasn’t been plowed yet therefore please slow down and be patient. The operator will eventually pull over when it is safe to do so to allow motorists to pass, so take your time, wait and be safe.
…Pull as far over to the right as is safe when you see a snow plow approaching from the opposite direction along an undivided highway. That way, you will be clear of any salt or winter abrasives.
…Give the snow plow operator a wave when they pull over to let you pass. They’re doing the job for you!
…Assume the snow plow operator can see you, especially if you’re driving too close and visibility is poor (which it often is in snowstorms). Your best defense is to keep your distance.
...Pass snow plows. It’s not safe. When drivers attempt to pass a plow truck, they put themselves, their passengers, the snow plow operator and other motorists at risk. The plow could be equipped with a wing blade on its left or right side, which can be obstructed by the snow it’s throwing. The plow also may be the first of a series of two to four more plows, staggered diagonally across the road to clear all lanes simultaneously. This practice is
called Echelon Plowing and would require the unwise driver to make multiple unsafe passes.
…Tailgate. Tailgating any vehicle puts you at risk of a collision; tailgating a piece of heavy equipment armed with plows only ups the consequences.
Drivers may not be aware…
Snow plows must travel slower than regular traffic when pushing snow and spreading salt and winter abrasives.
Snow plows stop at railway crossings to ensure it is safe to cross and that the plow blade will clear the track.
