This project will repair approximately 590 feet of the boat haven main breakwater

The Maritime Administration awarded America's Central Port District $4.55 million on March 23, 2026, under the National Infrastructure Investments program (CFDA 20.933) to repair and extend port infrastructure at Granite City Harbor in Mitchell, Illinois, with final completion by April 1, 2028.

The project comprises two distinct components. The first repairs approximately 590 feet of the Boat Haven main breakwater by re-grading the sand core and adding rock protection to damaged and eroded areas, achieving minimum design coverage depth. New rock placement and excavation occur above mean lower low water tide line within the original breakwater footprint; some existing riprap repositioning may occur below the tide line to stabilize the base for additional riprap. The second component extends the harbor's wharf by nearly 30 percent, creating approximately half an acre of additional working space and a contiguous 1,200-foot wharf capable of handling six barges simultaneously. This component includes installation of a sheet pile wall with drainage improvements, backfill and compaction behind the new extension, and removable safety rails. The wharf extension constitutes the first phase of the port's wharf improvement plan.

Performance metrics include quarterly measurement of total vessel calls per year and reportable events—safety or security incidents resulting in fatalities within 30 days, injuries requiring immediate medical attention, property damage exceeding $25,000, vehicle or vessel collisions, or life-safety evacuations.

The rehabilitation will be designed to tie into the adjoining U.S. Army corps of engineers USACE authorized structure. Activities to be performed this project will rehabilitate approximately 590 feet of the boat haven main breakwater. The project includes the following component component 1 construction and construction management. Repair approximately 590 feet of the boat haven main breakwater. RE grade the sand core and add additional rock protection to the damaged and eroded area to achieve the minimum design coverage depth. All new rock placement and excavation work is anticipated to occur above the 2 mean lower low water mllw tide line and within the original breakwater footprint. Some repositioning of existing riprap may occur below the 2 tideline to ensure a stable base for adding the additional riprap.
