| 摘要： | Work is underway to design a new, 1,200-foot lock chamber at LaGrange Lock and Dam on the Illinois River. The Rock Island Engineer District, working in conjunction with the Great Lakes and Ohio River Division, awarded the $33.2 million contract for the 100 percent engineering design to Tetra Tech on September 26. The new chamber will be built landward of the existing 600-foot chamber at Illinois River Mile 80.2. It will be constructed in the dry, and the 600-foot chamber will remain open both during construction and afterward, serving as an auxiliary lock chamber and providing redundancy to the system. |
