Probably the greatest advantage of Chicago as a location for our new facility is its excellent transport facilities. The city is served by three major railroads. Both domestic and international air cargo service is available at O’Hare International Airport; Midway Airport’s convenient location adds flexibility for domestic air cargo service. Chicago is a major hub of the trucking industry, and most of the nation’s large freight carriers have terminals there. Finally, except in the winter months when the Great Lakes are frozen, Chicago is a seaport, accessible through the St. Lawrence Seaway. topic sentence:_________________________________ support sentence 1:_____________________________ support sentence 2:_____________________________ support sentence 3:_____________________________ support sentence 4:_____________________________
