Draft Solicitation for Feedback - Lock and Dam 25 New 1,200 Ft Lock Navigation and Ecosystem Sustainability Program (NESP)
Constructing a new 1,200 ft Lock for Lock and Dam 25. The new lock at Lock 25 will be constructed in the downstream direction in the auxiliary miter gate bay, which has minimum provisions for an adjacent 360-foot-long lock and is referred to as Location 3 in the System Feasibility Study (September 2004). This contract will consist of construction of a new 1,200-foot drilled shaft-founded lock in the auxiliary miter gate bay, a 1,200-foot upstream ported guard wall, and a 650-foot downstream guard wall. The existing 600-foot lock will remain in place and once the new lock is constructed and operational, will become an auxiliary lock chamber used primarily by recreation traffic or when the 1,200 ft lock is out of service.
