MEMPHIS, Tenn. – Workers with the Tennessee Department of Transportation will reduce the Interstate 40 Hernando DeSoto Bridge over the Mississippi River near Memphis to one lane in each direction for approximately two months, beginning 9:00 a.m., September 7, 2010. Crews must reduce traffic on both the east and westbound side of the bridge to one lane in order to safely install a new seismic expansion joint along bridge piers located near the Riverside Drive exit. Located only sixty miles south of the New Madrid Fault, TDOT is reinforcing this nearly forty-year-old structure to be earthquake resistant.
