AUTHORIZATION:  The River and Harbor Act of 1945 provided the original authorization for the Locks No. 27 project. The Water Resources Development Acts of 1986 and 1992 provided further authorizations.

Chain of Rocks Canal

Location and Description:  Locks 27 is located in Madison County, Illinois, on the Chain of Rocks Canal at approximately Mile 185.1 above the mouth of the Ohio River in Granite City, Illinois. The main lock is 1,200 feet long and the auxiliary lock is 600 feet long. Due to extreme deterioration, funds were diverted from other needed maintenance to construct two major rehabilitation features (lock bulkheads; lift gate machinery for both leafs of the main lock and the downstream leaf of the auxiliary lock). The remaining major rehabilitation work includes replacement of main lock lift gate downstream leaf, culvert valves for both locks, lock bulkheads lifting beam, lock lighting, culvert valve machinery for both locks, main lock miter gate, downstream bulkhead sill stability anchorages in both locks, and upstream protection cell; and restoration of lockwall stability using drilled tiedowns.

Activities in FY 2010 ($173k)
- Complete design (culvert valve machinery, lockwall tiedowns)
- Manage contracts (fabrication, lock lighting, bulkhead sill anchors)

ARRA Allocation thru 28 Feb 10 ($10,985k)
- Fabricate culvert valve machinery (awarded)
- Install culvert valve machinery
- Complete design and construct tiedowns
- Complete design and fabricate main lock miter gate
- Complete design and construct upstream protection cell
- Install main lock lift gate
- Install main lock miter gate

Sponsor: Project is 100 percent federally funded.

Priority #1 – Deteriorated main lock lift gate will be replaced

Priority #2 – Deteriorated and leaking culvert valves will be replaced
