Investigators are looking into "what was blocked, what was not" along Interstate 70 when beams hanging from a crane struck a tractor-trailer Wednesday, a Maryland State Highway Administration spokesman said Thursday.
State highway officials and Maryland State Police are investigating the accident that critically injured a female passenger as the rig approached the Md. 66 exit of eastbound I-70, according to Maryland State Highway Administration spokesman Charlie Gischlar.
Two large support beams being used to install signs spun into the roadway at about 9 a.m., piercing the cab of the tractor-trailer and striking Evonne J. Whalen, 45, of East Bernstadt, Ky., in the legs, police said. Whalen's husband, Timothy Whalen, 53, was driving the rig.
Evonne Whalen was in critical condition Thursday afternoon at R Adams Cowley Shock Trauma Center in Baltimore, a hospital official said. Timothy Whalen was treated and released Wednesday from Washington County Hospital, a spokesperson there said.
