The initial footprint of the cofferdam on the Congaree River has been completed. The site is near the Gervais Street Bridge where crews are preparing the area to clean up coal tar, deposited decades ago, from the bottom of the river.
According to the Congaree Riverkeeper “the contractor will continue to build up the dam and then add concrete mats to armor and reinforce it. That process is expected to take another 5-6 weeks.” Click for Congaree Riverkeeper Facebook page
