The Lower Mainland is one of the busiest transportation zones in Canada with port facilities; rail and cruise ship lines; one international and three regional airports; ferry, bus and trucking terminals; and US border locations. It is a highly urbanized and rapidly growing region with the highest concentration of people and communities in the province and a magnet for tourism. While the area is generally subject to a mild coastal atmosphere, it can periodically experience severe wind, rain, and snow conditions.

The headquarters and main works yard for Mainroad Lower Mainland Contracting are located in Surrey’s Cloverdale community with supporting facilities in Delta and Langley.

Specific road maintenance challenges include:

  • Communications/traffic monitoring and control
  • Concentrated population base
  • Environmental issues
  • Ferry and port terminals/international border crossings
  • Freeways, major bridges, swing bridges, HOV lanes
  • Heavy and high speed traffic routes
  • Large and diverse stakeholder groups
  • Major bridge structures
  • Traffic control flow operations (bridge and tunnel)
  • Signs

Service Area

The Lower Mainland Service area: 1,525 kilometres of roadway including 626 major structures (e.g. bridges, retaining walls, culverts, and sign structures) and a wide array of signage ranging from a single face on a post to a face on a sign bridge spanning multiple lanes.

With a large and concentrated population in the Lower Mainland and limited access routes, emergency planners have developed a network of roads as disaster response routes. Mainroad’s crews and management staff are designated “first responders” in the case of an earthquake or other disaster in the region and take that added responsibility very seriously.
