A 13-year-old girl died Thursday of head injuries suffered in a freakish car accident caused primarily by large potholes in the road.

Erin Walker, Cedar Hills, died at 10 a.m. at University Hospital in Salt Lake City.Deeann Walker, 4187 W. Sage Road, Cedar Hills, the girl's mother, was traveling east on 26th North in Pleasant Grove on Wednesday morning when she swerved into the other traffic lane to avoid a series of potholes. When she corrected back into her lane, she hit a patch of black ice and slid off the road, striking a utility pole with the car's left rear passenger side.

The impact sheared off the door, and the girl, who was riding in the back seat, hit her head on the pole during the impact. Officer were unsure if the victim was wearing a safety belt.

Walker was taken by ambulance to American Fork Hospital and then transported by helicopter to University Hospital. Her mother was treated at American Fork Hospital for superficial injuries and released. Another daughter, Andrea, 15, also riding in the back seat, was not injured.

Ironically, the Pleasant Grove City Council on Tuesday evening had discussed the poor condition of 26th North, which connects Pleasant Grove and American Fork.

The north traffic lane of the road is owned and maintained by Utah County, while the south lane is owned and maintained by Pleasant Grove - resulting in uneven upkeep.

Pleasant Grove Public Works Director Frank Mills contacted Utah County engineer Clyde Naylor on Wednesday and sought the county's participation in resurfacing the road this spring. Naylor said the county will work with Pleasant Grove but noted that potholes will be a serious problem throughout the county this spring.
