One person missing, one rescued, after two people jump from icy Little Red River bridge to avoid jack-knifed tractor trailer.

A search was called off because of darkness early Saturday night for one of two people who jumped from an interstate bridge in southwestern Arkansas into an icy river to avoid a jackknifed 18-wheeler that was skidding toward them.

The search for the missing person along the Little Red River was to resume Sunday morning, according to Keith Stephens, a spokesman for the Arkansas Game and Fish Commission, which was leading the search.

"The water is 25 feet or less, so it's pretty shallow," Stephens said. "But the current is pretty high from the snow and ice from the storms."

The missing person's name was not released.

Three people were outside their vehicles after an earlier accident on the icy Interstate 30 bridge near Fulton, Ark., when a commercial truck jackknifed and slid toward them. Two people leapt over the guardrail and into the water during 29-degree weather.

One person was recovered almost immediately, according to Arkansas State Police spokesman Bill Sadler.

Game and Fish Commission employees and water rescue units from Hempstead and Miller counties were called to the scene.

The bridge eventually was cleared and traffic flowed again, though roads were treacherous.

Snow swept into Arkansas from Texas and Oklahoma on Friday, generally leaving 2-4 inches in a swath from the Ouachita Mountains to near Memphis, Tenn. Schools dismissed early, but in the Little Rock metro area the snow came late in the evening rush hour and tied up traffic for hours.

"They need to pay attention to these hills," said Mark Townsend of Little Rock, who bought chains Saturday morning. In the bank parking lot where he abandoned his Cadillac overnight, he worked to connect the chains to his rear tires and said he had gotten within a mile of home Friday night before traffic snarls ended his commute.
