“Did you know that hidden just three miles offshore from Wilson Avenue is a structure with a fascinating history?” That’s the Wilson Avenue Breakwater Light. It’s not just a light; it’s a sentinel of Chicago’s past.
Let’s dive into the story of the Wilson Avenue Breakwater Light. It began in 1915, a time when Chicago was rapidly expanding. The city needed clean water. The Chicago River was becoming a cesspool. So, the city looked to Lake Michigan.
The Wilson Avenue Breakwater Light marks the location of the Wilson Avenue Crib. This crib was vital for drawing fresh water from the lake. Construction began in 1915 with the sinking of a massive steel caisson. It measured ninety feet in diameter. Granite blocks formed the superstructure. This protected a forty-foot inner well chamber.
An eight-mile-long tunnel connected the crib to the pumping station onshore. This was a tremendous feat of engineering. Workers toiled tirelessly to dig these tunnels.
Interestingly, engineers discovered a problem during construction. The superstructure was eighteen inches out of plumb. To fix this, they blasted away concrete. They then used three hundred jacks to level the structure. This delicate operation delayed completion until May 1, 1918.
On October 23, 1915, the Wilson Avenue Intake Crib Light was first established. It marked the new crib during its construction. Initially, a fixed white light shone from a wooden post. It stood thirty-five feet above the water. A fog bell also sounded every fifteen seconds.
Once completed, a red circular tower was mounted atop the crib. It housed a lantern room. This served as a permanent navigational aid. The tower initially used an acetylene light. It could be seen for up to eight miles. A fog bell struck a double blow every twenty seconds during low visibility.
Life on the Wilson Avenue Breakwater Light wasn’t easy. Crews battled harsh winters. They had to prevent ice from clogging the water intake. Sometimes, they even used small dynamite charges. This was a dangerous but necessary remedy.
The keepers also maintained the light. They cleaned the lantern glass. They ensured the light remained a beacon for mariners. Crews worked in shifts. They were transported to and from the crib by Water Department tugs. Despite the challenges, living conditions were good. The quarters were spacious.
Today, the Wilson Avenue Breakwater Light still stands. It serves as an active aid to navigation. A Tideland Signal 300mm optic, powered by city electricity, now lights the way.
Though the glass has been removed from the lantern, it remains a sentinel. The Wilson Avenue Breakwater Light reminds us of Chicago’s ingenuity. It is a testament to the city’s determination to provide clean water. Next time you’re near Wilson Avenue, remember the Wilson Avenue Breakwater Light. It is a beacon with a fascinating story.
