Eagle-eyed motorists traveling east on part of U.S. 80 in Warren County will see new road signs paired with the old familiar “80.”

The new signs were posted as part of a designation that became official years ago, but they won’t affect addresses for homes and businesses.

About six miles of the highway between the Beechwood intersection, at Mississippi 27 and East Clay Street, and Bovina was decommissioned by the federal government and designated Mississippi 822 about the same time Interstate 55 was completed in the 1970s, Mississippi Department of Transportation Central District Engineer Kevin Magee said.

During a recent replacement of highway signs in the district, the oversight was corrected to show it’s a state highway for listing purposes, though the road is eligible for federal money on improvements just as any other state highway, he said.

“We’ll still be able to get federal money for maintenance on it,” Magee said.

Kenny Staggs, the county’s addressing coordinator, said 283 addresses are on the books in the stretch. State law does not mandate that addresses change.

“It will still be Highway 80 for emergency responders,” said District 1 Supervisor David McDonald, who chairs the E-911 Commission. The seven-member board oversees emergency dispatch and recommends new road names and name changes to the Board of Supervisors.

It’ll also remain U.S. 80 on official state maps issued by MDOT, Central District Commissioner Dick Hall said.

“I grew up in Vicksburg, and it’s always been Highway 80 to me,” Hall said.

U.S. 80 was among the nation’s first commissioned highways and was the first all-weather, coast-to-coast route for travelers. Currently stretching from Dallas to Tybee Island, Ga., its original western terminus was in San Diego but was decommissioned in California in segments starting in 1964.
