ST. CHARLES COUNTY, MO (KTVI) - The lack of a shoulder on the Daniel Boone Bridge may have cost a young woman her life on Thursday.

Stephanie Phung of O’Fallon, Missouri was stopped in the right-hand lane on the Boone Bridge when she was struck and killed about 9:30 a.m. The accident forced the shutdown of the westbound lanes of I-64/40 at Spirit of St. Louis Boulevard for four hours.

Phung, 28, was crossing the Missouri River to Saint Charles County when she struck a loose tire in the middle of the roadway. It became lodged beneath the car.

Missouri Highway Patrol Sergeant Al Nothum said Phung pulled her disabled passenger car over as far as she could to the right, but there was no shoulder lane there.

Phung got out of her vehicle and was looking at the car when one driver swerved and barely missed her, but the second driver was unable to swerve over enough. His pickup truck struck and killed her.

“These are really judgment calls depending on the situation. Every situation is different," Nothum said.

Nothum urged drivers who are stalled on roadways to put on their vehicle flashers and call for help by dialing 911 or *55. If you cannot seek safety away from the traffic, he recommended remaining inside your vehicle, but noted, "There is no guarantee there, either."
