A plank road is a dirt path or road covered with a series of
planks, similar to the wooden sidewalks one would see in a Western
movie. Plank roads were wildly popular in Ontario, the U.S.
Northeast and U.S. Midwest in the first half of the 19th century.
They were often built by turnpike companies.
In 1836 the plank road steaming from Chicago was completed. The
in 1851 it was extended southward to Naperville. And then form
there several more were created to connect the southern cities
including Joliet and New Lenox.
During this construction one of the first Illinois Toll Booths
was constructed on this spot. On the first stretch of the
Southwestern Plank Road, the tolls were 12 1/2 cents (one "bit")
for a man on horseback, two bits for a single team, and three bits
for a 4-horse vehicle.
To find this preform tube look into the eyes of the buffalo. He
is looking in the opposite direction of the cache. Go the opposite
way for about CD feet. Where the year the booth was approximately
built is ABCD. Happy hunting.
