DETROIT -- The U.S. Army Corps of Engineers will be conducting structural stabilization work at the Grand Haven south pierhead between July 9-13. This project will require temporary closures to pedestrian traffic near the lighthouse to ensure public safety.
During this timeframe, construction crews will place approximately 300 tons of 5- to 10-ton armor stone at the end of the south pierhead. This new material will supplement the existing armor stone in the area to provide additional protection to the pierhead and stabilize loose sheet piles.
"This armor stone placement is a critical interim measure to protect the integrity of the south pierhead," said Liz Wilkinson, U.S. Army Corps of Engineers, Grand Haven Office operations manager. "By stabilizing the loose sheet piles now, we are preventing further damage while our team continues to finalize the design for a permanent, long-term fix to the structure."
The construction vessel and equipment are scheduled to be on-site during the July 9-13 window. While the placement of the stone is highly efficient and expected to take only half a day, the exact timing of the operation depends entirely on favorable weather and wave conditions.
"Because we are at the mercy of the weather, we cannot pinpoint the exact 12-hour window the work will occur within those five days," Wilkinson said. "However, whenever the plant is actively placing stone, the pierhead will be strictly closed to all pedestrian traffic at the lighthouse. We ask the public to respect all safety perimeters and appreciate the community's patience as we complete these necessary repairs."
Visitors to the Grand Haven waterfront should anticipate restricted access near the lighthouse during active construction hours and are encouraged to maintain a safe distance from all heavy equipment.
The Detroit District oversees 3,150 miles of shoreline, 81 harbors and channels connecting the Great Lakes, and manages projects across Michigan and parts of Indiana, Wisconsin, and Minnesota.
