This coastal canal is used to transport of millions of tons of cargo each year. This cargo is moved aboard
barges at a much cheaper cost, when compared with trucks, railcars, or airplanes. Barge transport is also a
much safer way to move hazardous (dangerous) materials. This waterway, therefore, is referred to by many
as "The Most Important Highway in North America". It is over 1,400 miles long, running from the
US/Mexican border all the way to South Florida. You could leave Matagorda, use it to connect to other
waterways, and travel to Minnesota or New Jersey without ever getting off the boat. Its name is? (check

_____ the Gulf Master Shipping Lane
_____ the Houston to Galveston Ship Channel
_____ the Colorado River Barge Canal
_____ the Gulf Intracoastal Waterway
_____ the Mississippi River Highway
