"It sounded like a jet airplane," he recalled, looking out at the river. "I had nightmares for a long time after that."

Like most Point Pleasant residents old enough to remember that day, Darst, now 70, has vivid recollections of Dec. 15, 1967. He not only saw the bridge fall but had driven across it hours before, and he remembers a feeling of unease.

A traffic light had been malfunctioning all day, causing cars and trucks to back up on the bridge, which had linked Point Pleasant and Kanauga, Ohio, since 1928. Darst said he felt anxious waiting in traffic and eventually pulled out and sped off the bridge by driving in the opposite lane.

"I could feel something was wrong. Something was in the air," he said.

Of the 46 who died in the collapse, 22 were from Ohio and 19 were from West Virginia, including 15 from Point Pleasant. The others were from Virginia and North Carolina.

Today, there's almost nothing to indicate where the bridge once stood. A small plaque marks the spot on Main Street where a ramp brought motorists onto the bridge, but the ramp itself is long gone.

The Point Pleasant River Museum, a few blocks from the old bridge, is working to make sure that absence doesn't extend to the town's collective memory.

The museum is trying to convince everyone who remembers the collapse, one of the country's worst-ever bridge disasters, to share their recollections in videotaped interviews that will be archived for residents and historians.

"We're kind of the focus for the remembrance of it," said Jack Fowler, executive director of the museum. "We decided we really needed to have these archived at the museum."

This month, the museum is exhibiting dozens of rare photographs of the disaster, along with debris from the collapse. Among the stark images and pieces of gnarled metal, a steady stream of residents have been interviewed about their memories.

Bob Rimmey was at a cab stand in front of the Mason County Courthouse, about 250 feet from the bridge.
