A 48-year-old woman who was walking on the eastbound shoulder of Highway 104 was hit by a passing vehicle on Tuesday morning and was seriously injured, said Nova Scotia RCMP.

RCMP in Pictou County rerouted eastbound traffic between Exits 19 and 20 — near Salt Springs — for several hours as they investigated the crash. That section of the highway was reopened at 4 p.m.

Police said the woman is from Limerock, which is west of New Glasgow and near Salt Springs, where the accident happened. She was taken to the Aberdeen Hospital in New Glasgow.

A collision analyst was brought in to examine the scene.
