Beginning in the late 1940’s MK built and still performs a triad of construction in the Port of Portland. It consists of marine terminals, located along the Willamette River and the Columbia River that are served by rail, that connect interstates and river barges. The company takes great pride in the part we played in pulling all these ends to the middle that resulted in over one thousand businesses and corporations using the Port’s marine facilities and over 12 million tons of cargo moving through the Port each year.
