From Martland, Carl D. ”Example of the Ability of Civil Engineering Projects to Shape Cities and Channel Development:Roads, Canals, and Railroads in the Early 19th Century” MIT, Spring 2005http://ocw.mit.edu/NR/rdonlyres/Civil-and-Environmental-Engineering/1-011Spring-2005/5B684A1B-4A5A-4419-AB9C-6347D6CD1AD4/0/p_eval04_l2_19cn.pdf
