Massive Cross Culverts Installed at Charleroi Lock and Dam
The precast, 115-tons culverts were brought in and lowered into place using a large A-frame crane. The 12-ft-high by 14-ft-wide by 34.5-ft-long precast culverts are stay-in elements within the new middle wall that will allow the future landside lock chamber to empty water from the chamber into the river.
