| 摘要： | The Chicago Harbor Lock reopened April 15 after a five-month closure to reconstruct a portion of the north chamber wall, with similar closures expected over the next four winters. The closures are part of a larger rehabilitation project being conducted due to the age of the 600- by 80-foot lock, built between 1936 and 1938 by the Sanitary District of Chicago as a component of plans that reversed the flow of the Chicago River so that it flows away from Lake Michigan instead of into it. "Exploratory demolition was conducted and interim repairs completed," said Tim Kroll, chief of the Chicago Engineer District's operations branch. "Wall resurfacing will continue over the next two winters, into the spring of 2024." Following the work on the north and south chamber walls, a separate contract will replace the lock's concrete slab flooring with trimming concrete laid in two sections through April 2025, project manager Mike Nguien said. |
