Morganza Spillway Structure (ORCS), in use since 1963, where floodgates are routinely used to redirect the Mississippi's flow into the Atchafalaya River such that the volume of the two rivers is split 70%/30%, respectively, as measured at the latitude of Red River Landing. During the 1973 Mississippi flood, the ORCS was being damaged due to high flow rates, leading to the opening of the Morganza Spillway to help relieve this pressure. Subsequently, the nearby Old River Control Auxiliary Structure (ORCAS) was constructed, adding additional floodgates for use during major floods. The Morganza Spillway, about downriver from ORCS and ORCAS, is designed for
Maryland Route 242 in 1923. The state highway was reconstructed with curve modifications and a bituminous-stabilized gravel surface in the 1950s, beginning with the Morganza–Clements section in 1949 and 1950. MD 242 was rebuilt from Clements to Bushwood by 1959. Maryland Route 242 Maryland Route 242 (MD 242) is a state highway in the U.S. state of Maryland. Known as Colton Point Road, the state highway runs from Coltons Point north to MD 5 in Morganza. MD 242 connects the communities of Morganza, Clements, Bushwood, Avenue, and Coltons Point in western St. Mary's County. The state highway also leads to St. Clement's Island
