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