Some local residents got the chance to take a walk where not many people have gone before. They took a stroll on the Keokuk-Hamilton lock and dam.
The lock and dam between Keokuk and Hamilton celebrated 100 years of service this weekend. Click here to see the website.
How important is the lock and dam to the area?
Just take a look at the Mississippi River.
In 1913, this dam was built to make river flow more manageable. According to the Keokuk Iowa Tourism site, when it was completed it was the "largest electricity generating plant in the world."
A hundred years later, there's a celebration to be had.
"This celebration included some never before seen areas of the dam. Security restrictions were lifted and the public was allowed to travel across the dam on trolley or just walk around it. It's a truly a once in a lifetime opportunity," MRP 100 Committee Coordinator Phil Tracy said.
"Although on Monday it'll be business as usual, one thing is for sure," Tracy said. "No one is going to forget the view they got this weekend."
If you didn't get a chance to visit the celebration today, you're in luck.
The celebration continues Sunday in both Keokuk and Hamilton.
