||To pay for the
canal, the U.S. Congress gave the State of Illinois
235,000 acres in the form of alternate sections of land
in checker-board fashion,36 to be sub-divided and sold. It
must have been slow going. The highest price paid in the
first sale was $10037 for an eighty by one hundred eighty
foot lot on the river in downtown Chicago. Work was begun
in 1836 and completed in 1848. The canal was an immediate
success and in 1882, traffic peaked at over one million
tons,38 more than the combined shipping total at the ports
in New York, San Francisco, and New Orleans.39 The portion of the canal in
Chicago was covered over by the construction of the
Stevenson Expressway. Between Channahon and Ottawa much
of the canal is still to be seen, with the towpath
providing a delightful hiking and biking trail.
Other continental divide crossings had been developed elsewhere in the country. In upper New York State, a trench was dug to connect the Hudson River and Lake Erie. The Erie Canal provided a link between the Atlantic Ocean and the Great Lakes. Nearby, a short canal was completed in 1819 at the north end of the Hudson connecting to Lake Champlain, which drains into the St. Lawrence. This route allowed boat traffic from New York City to Quebec. In the South, a waterway was envisioned which would connect the Atlantic Ocean with the Ohio River system, over the Alleghenies. The route was to be from Chesapeake Bay along the Potomac River to its source, and then over the divide to the Ohio at Pittsburgh. Work was started in 182840 and the canal was completed as far as Cumberland, Maryland. Construction was halted in 1850, not because the canal was unfeasible, but because the Chesapeake and Ohio Railroad had been completed eight years earlier. In the unknown West, there was a dream of a water route, a northwest passage, to the Pacific Ocean. The dream lasted from the time of earliest exploration until finally the expedition of Lewis and Clark proved that the Rocky Mountains were a formidable barrier and a connection from the East to the West water systems would be neither easy nor short.
