Grafton Lime Kilns
This park was once part of a limestone quarry operated by the Milwaukee Falls Lime Company, incorporated in 1890. Five vertical kilns were built for burning limestone from the quarry on the site to make quicklime. The kilns were built of stone lined with firebrick. The fasteners on the timbers are nuts threaded onto long steel rods through the structures to reinforce them.
The kilns were fueled with cordwood, creating temperatures from 1,400 to 2,000 degrees Fahrenheit, converting calcium carbonate to calcium oxide or lime, which when mixed with water, was widely used in construction and for tanning hides.
Mules pulled the trams of limestone from the quarries to the crusher, and then cables pulled them on tracks atop the kilns, which were stoked with cordwood in the fireboxes below. When the limestone was dehydrated, it was pounded into a fine powder which was used for plaster, mortar, fertilizer, and white wash. A spur line carried the processed lime to the main line of the old Wisconsin Central Railway for shipments to Milwaukee, Chicago, St. Louis and Detroit. By the spring of 1901, the Milwaukee Falls Lime
The three remaining kilns were restored many years ago, and serve as monumental reminders of Grafton's industrial activity and related history during the late 19th and early 20th centuries.
In 1888, this iron bridge was built across the Milwaukee River at Bridge Street to replace the original wooden one, maintaining the only access to the village from the east. Built by the Wisconsin Bridge and Iron Co. of Wauwatosa, the old iron bridge was the main entrance into the Village for many years. This riveted iron bridge was the only way across the Milwaukee River in the Village of Grafton until 1928 when the new concrete bridge on Washington St. was built to handle increased car and truck traffic.
The bridge is an iron truss bridge comprised of seven modules - a triangular module on each end and five rectangular modules in between with diagonal tension rods in all five. The riveted assembly has a cast iron sign at the top reading "1888 BUILDERS WISCONSIN BRIDGE & IRON CO. WAUWATOSA WIS." The deck is made of heavy wooden planks and was single lane to accommodate horse-drawn wagons. Tension rods run along each side below the deck level. The entire bridge was coated with aluminum paint after being moved from its original location on Bridge
The bridge was moved to the Lime Kiln Park in 1996, when the bridge was replaced by a concrete one. It is one of the few remaining steel truss bridges in Wisconsin.
