The project, which consists of repairs to dam gates, is scheduled to begin Tuesday.
In September, the U.S. Army Corps of Engineers awarded a $2.6 million contract to Construction Services Group from Charleston. Subcontractors, including Augusta Industrial Coatings, will assist in the repairs.
According to a corps release, the repairs should not affect lake levels.
From 2010 to 2012, contractors repaired the lifting arms and applied a new protective coating on the spillway gates as part of the American Recovery and Reinvestment Act, which resulted in a similar lane closure on U.S. 221. During that project, the corps was required to maintain lake levels at least two feet below full pool to ensure worker safety.
