Canal cross-sections
Cross sections of the Illinois & Michigan Canal in comparison with various other well known canals.The I & M was not a huge canal, partly because it was built so early and because canals are expensive to construct. The state could hardly afford to build the I & M canal, but it fostered Chicago's spectacular growth, and by the late 1890s Chicago was able to pay for the construction of the Sanitary Canal.
