What is the road/highway service area that Mainroad Mid-Island Contracting is responsible for maintaining?
The Mid-Island Vancouver Island Service Area 2 is 3,259 lane kilometers of roadway covering Central Vancouver Island roughly between the communities of Chemainus (North Cowichan) and Bowser (Regional District of Nanaimo).
Within the boundaries of the Service Area, there are:
Two major ferry terminals
- Highway 1 at Departure Bay
- Highway 19 at Duke Point
Two gulf islands
- Gabriola Island
- Lasqueti Island
The southern boundary of Service Area 2 adjoins Service Area 1 on Highway 1, and the northern boundary of Service Area 2 adjoins Service Area 3 at Cook Creek Road on Highway 19 and Highway 19A. Trans-Canada Highway 1 and Highway 19 are the only major numbered routes running south to north on Vancouver Island.
Service Area 2 encompasses the cities of North Cowichan (Chemainus Village), Ladysmith, Nanaimo, Lantzville, Parksville, Qualicum Beach, Port Alberni, Bamfield (unincorporated), Ucluelet and Tofino. Along with these cities, there are four regional districts including Cowichan Valley Regional District, Regional District of Nanaimo, Alberni Clayoquot Regional District and Powell River Regional District.
The service area includes the maintenance of approximately 194 bridge/culvert structures,
4 rest areas, 2 pedestrian overpasses, 20 sign bridges and approximately 56 retaining wall structures.
*Please Note: Mainroad is not responsible for plowing within municipal boundaries or on forestry service roads and any snowplow discharge falling on residential driveways is the responsibility of the property owner.
Mainroad’s contract with the Province does not include road/line marking. Pavement marking is a separate maintenance contract with the Province held by LaFrentz Road Marking. Please contact LaFrentz Road Marking 1-800-859-2947 | www.lafrentz.ca
Mainroad is not responsible for ice and snow maintenance around mailboxes.
Where are Mainroad's maintenance yards located?
The headquarters and primary works yard for Mainroad Mid-Island Contracting is in Parksville with supporting works yards in:
- Duke Point
- Port Alberni
- BC’s Gulf Islands | Gabriola and Lasqueti
How many Mainroad employees are working during winter operations?
Our fleet and crews are fully engaged in winter maintenance operations. Up to 50 employees plus mechanical support are available to work around the clock to keep our roads clear.
How does Mainroad monitor weather and highways conditions?
As the weather can change rapidly on Vancouver Island, Mainroad is continuously monitoring weather and highway conditions Mainroad is constantly monitoring weather and highway conditions. To determine how best to protect motorists, we oversee weather in two ways:
1. Monitoring: Mainroad uses MARWIS, is a mobile road weather information sensor that measures road conditions and environmental data both reliably and professionally. The sensor is directly installed on the vehicle to collect weather data such as temperatures, humidity, and dew points. This helps our crews manage the road surfaces.
Road Patrols: Prior to and during a storm event, our operators are on the road observing current conditions and making the calls as to what maintenance is required.
2. Forecasting: Mainroad uses data derived from Road Weather Information System (RWIS) stations throughout our maintenance areas for weather forecasting.
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. Mainroad contracts with a leading road weather forecaster, which watches over B.C. weather 24 hours a day, seven days a week.
Environment Canada also contributes to our weather watch, providing regional forecasts. Combined with additional weather information from other sources, 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.
What is Mainroad doing to prepare for a winter storm event?
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 anti-ice 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 fleet and crews will be engaged in winter maintenance operations. Over 50 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.
What materials does Mainroad use for winter road maintenance and when are these materials applied?
Mainroad primarily uses two materials in the Lower Mainland for winter road maintenance: anti-icing brine and de-icing salt with winter sand as required. The use of a specific material is determined by the forecast, actual weather conditions and in accordance with the standard set by the Ministry.
Anti-icing Liquids (brine): Anti-icing liquids are 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. Brine can also act as a de-icing agent during a storm or once a storm has passed and can help to remove packed snow and ice from the road surface. After snow has been cleared, liquid anti-icing brine is an important component in Mainroad’s plan to prevent ice from forming as it breaks down the bonding ability of ice on the road surface.
Salt: Salt is a staple of our winter maintenance routine. Sometimes salt is used in a liquid (salt brine), sometimes in a solid. Salt melts the ice and dissolves the snow into slush or water but if the snow keeps coming, it will dilute the salt and make it less effective. Salt is only effective in certain temperatures. If temperatures fall below -5C, salt becomes less effective.
Winter Sand: The winter sand used by Mainroad is a graded material specified by the Ministry of Transportation and Infrastructure. Winter abrasives improve traction. During a snow event, restoring traction will be completed by either applying winter abrasives on compact sections or by applying winter chemicals to compact sections to melt snow and ice when pavement temperatures are above -9C.
The use of a specific material is determined by forecast and actual weather conditions.
Why are some roads plowed more than others? Which streets get plowing priority?
Mainroad’s response 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 because those are the ones used by emergency services and the majority of traffic. 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.
What is Mainroad doing to respond to changing conditions during a storm event?
Weather can change rapidly on Vancouver Island which is why Mainroad is constantly monitoring weather and highway conditions. During a storm event, Mainroad crews will be working to clear the highway surfaces as quickly as possible. When temperatures permit, we will commence anti-icing operations with the goal of getting the compact snow off service area highways and roads. On primary routes, we will aim to have bare and black conditions from the completion of the weather event as quickly as possible however challenging weather will not always permit us to have bare and black conditions on secondary routes. During every storm event, Mainroad will provide the Ministry and Media with regular updates.
Other Types of Winter Storm Response
Clearing down trees and vegetation after other types of winter storms such as a windstorm 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 three (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.

Who ensures the work is being done properly?
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. Mainroad has a very good performance rating, as measured against our contractual commitments.

Give your vehicle a winter check-up and equip your family with a winter survival kit so you’re not caught off guard when weather conditions deteriorate.
We encourage drivers to choose the best winter tires possible when driving in snow and ice, and to ensure tires are in good condition, with a minimum tread depth of 3.5 mm.
Carry an emergency survival kit with non-perishable food, blankets and first aid supplies, windshield scraper and snow brush, extra windshield washer fluid, fuel line antifreeze, flares and matches or lighter, tire chains and gloves, shovel and traction mat, sand or kitty litter, flashlight and extra batteries, battery jumper cables, spare tire wheel wrench and jack, extra clothing and footwear and sandbags for extra weight.
Driving during winter driving conditions
- 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.
TranBC Link: How to drive around snow plows in British Columbia
Snow Plow Safety Do’s and Don’ts
Do……Turn on your head and taillights during heavy snow or rain, even during the day.
Do……Use winter-rated snow tires with the mountain-snowflake symbol.
Do……Watch for the flashing amber lights. It can be difficult to see snow removal equipment.
Do… …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.
Do……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.
Do……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.
Do……Give the snow plow operator a wave when they pull over to let you pass. They’re doing the job for you!
Snow Plow Safety Do’s and Don’ts
Don’t……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.
Don’t……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.
