For 24 hours, the Mississippi River navigation channel will be closed to barge traffic, starting at 6 a.m. Saturday, May 30.
During this time, crews will be taking down the work platform that was used when they put up the keystone that connected the basket-handle part of the new bridge.
Recreational boaters are asked to avoid the construction area when possible. Boaters should slow down and obey no-wake zones.
This statement from project leaders explains why:
“Even a small boat traveling at high speeds can affect barges and cranes on site. When the water gets choppy, barges will sway despite being anchored in the riverbed. While it’s not very noticeable when standing on the barge, the movement gets magnified at the top of the cranes sitting on the barges. These cranes are lifting our crews as well as heavy materials up to the arch, and unexpected barge movement can pose a serious danger.”
