State highway engineers on the Arkansas and and Tennessee sides of the Mississippi River say they have summoned national experts in bridge repair to speed up re-opening the Interstate 40 bridge over the river at Memphis as quickly and as safely as possible.
One day after a routine inspection detected a fracture in one of four 900-foot beams supporting two bridge spans near the Tennessee side of the river prompted an emergency shutdown of the major river crossing for truck traffic in the nation's mid-section, state highway officials said it remains too early to say when barge traffic could resume on the river, never mind traffic on the bridge, which carries more than 40,000 vehicles daily, a third of them trucks.
"It is a significant fracture in a steel beam that is [central] to the integrity of the bridge," said Lorie Tudor, the director of the Arkansas Department of Transportation, at a noon-time briefing in Little Rock to discuss the steps being taken to identify how to repair the 50-year-old bridge.
MEMPHIS — The Interstate 40 bridge connecting West Memphis and Memphis remained closed Wednesday after inspectors found a crack in the span a day earlier.
The bridge was shut down Tuesday afternoon after the crack was discovered during a routine inspection, the Arkansas Department of Transportation said.
The department said it was working with the Tennessee Department of Transportation to ensure the 48-year-old, 1.8-mile bridge is safe before reopening.
Traffic was being rerouted to the 71-year-old Memphis & Arkansas Bridge that carries Interstate 55 into Memphis, about 3 miles south of the I-40 span. River traffic was also shut down until further notice, the Tennessee Department of Transportation said.
Road traffic appeared on Tennessee Department of Transportation cameras to be moving steadily on the I-55 bridge on Wednesday morning.
In an inspection for the 2020 National Bridge Inventory report, the Federal Highway Administration said the I-40 bridge checked out in fair condition overall, with all primary structure elements sound and only some minor cracks and chips in the overall structure. Its structural evaluation checked out "somewhat better than minimum adequacy to tolerate being left in place as is."
However, height and width clearances for oversize vehicles were "basically intolerable requiring high priority of corrective action," the inspectors found. Tennessee recommended "bridge deck replacement with only incidental widening."
The bridge, which opened in 1973, carried a 2020 average of 35,000 vehicles a day across the Mississippi River, 29% of them trucks, according to the report. Its traffic volume was expected to increase to 56,000 vehicles per day by 2040.
