U.S. 90

U.S. 90 travels along the Mississippi Gulf Coast through Hancock, Harrison and Jackson Counties. The highway enters the Magnolia State through rural Pearlington and comtinues east to Waveland and Bay St. Louis. Spanning St. Louis Bay, U.S. 90 heads to Pass Christian then Long Beach, Gulfport and Biloxi. Crossing Biloxi Bay, U.S. 90 enters Ocean Springs. East from there, the four lane highway leads to Gautier and over the East Pascagoula River to Pascagoula. Turning northeast from Moss Point, U.S. 90 leaves Mississippi adjacent to Interstate 10.

The landfall of Hurricane Katrina on August 29, 2005 impacted substantial portions of U.S. 90 across Mississippi. Bridges over St. Louis Bay and Biloxi Bay were virtually destroyed by the powerful storm surge from Mississippi Sound. The highway also was washed away along the coastal route between Pass Christian and Gulfport. Recovery efforts included constructing new fixed high level spans across St. Louis Bay, between Bay St. Louis and Henderson Point, and across Biloxi Bay from Biloxi east to Ocean Springs.

East into Jackson County, U.S. 90 joins the cities of Ocean Springs, Gautier and Pascagoula. A rural segment remains along the highway between Mississippi Highway 57 and Gautier. Crossing the West Pascagoula River, U.S. 90 traverses a causeway east to an interchange for MS 617 south to the Port of Pascagoula and Pascagoula Naval Station. A high level span, built in 2002, replaced the draw bridge over the East Pascagaoula River into Pascagoula. Following Denny Avenue, a four lane commercial arterial, U.S. 90 turns northeastward from near Downtown Pascagoula to eventually run alongside a CSX Railroad to rural areas preceding the Alabama state line.

The 1960s-era Biloxi Bay Bridge connecting Ocean Springs with Biloxi along U.S. 90 was destroyed by the storm surge of Hurricane Katrina on August 29, 2005. The ground breaking ceremony for the previous bridge took place on June 24, 1960 (The Greenwood Commonwealth, 1960). The 7,700 foot long span cost $7 million to build (Enterprise-Journal, 1959). The old Biloxi Bay Bridge included a draw span with a vertical clearance of 40 feet and horizontal clearance of 132 feet (Enterprise Journal, 1959).

U.S. 90 converges with Interstate 10 east of Franklin Road at the state border. Prior to completion of I-10 in Mississippi, U.S. 90 directly connected to the freeway east toward Grand Bay and Mobile, Alabama.
