The Redfish to Bayport Ship Channel and Bayport Ship Channel projects are located in Galveston Bay and Trinity Bay. The primary goal of Redfish to Bayport is to widen the ship channel to a minimum of 700 and the Bayport Ship Channel feet to approximately 455 feet to Mitigate for oyster habitat loss and construct marshes and three bird islands in Galveston Bay. The Bayport Ship Channel will widen the ship channel to approximately 455 feet. The length of both projects are approximately 12.3 miles in length.
