Trans4Media has partnered with the Washington State Department of Transportation to provide advertising opportunities on all of the Washington State Ferries(WSF) vessels and terminals. WSF is the largest Marine Transportation system in the United States, and the largest vehicle ferry system in the world. Over 25 million passengers travel through the Ferry System each year. What we do for Washington State Ferries is pretty cool. We are actively pursuing other venues to partner with. If your operation or municipality could use some extra revenue, please be in touch: info@t4media.net
