LEWISTON — Traffic in the Twin Cities was backed up most of Monday afternoon into the evening after a two-vehicle crash in Little Canada sent a utility pole and transformer crashing to the ground just before 1 p.m.

A woman was treated for apparent injuries following a two-car accident that clipped a utility pole and closed two blocks of city traffic for most of the day.

Officials expected to reopen both lanes of traffic on Bernard Lown Peace Bridge sometime after 8 p.m. Monday.

Crews from Central Maine Power, Oxford Networks and Time Warner Cable worked most of the day to replace the utility pole, transformer and downed lines. In addition, a crew from the Maine Department of Environmental Protection was there throughout the day cleaning up fluids from the transformer.

A 2010 Toyota Sienna minivan driven by Audrey Hemond, 78, of Lewiston and a 2000 Chevrolet pickup truck driven by Dennis Stevens, 46, of Lisbon were southbound toward Auburn on Cedar Street. The pickup truck apparently tried to pass the minivan, which moved to try to avoid it, police said. The truck struck the minivan, then careened into a utility pole, shearing the pole and causing wires to drop to the pavement, police said. The truck continued down Cedar Street onto the sidewalk and came to rest against a chain-link fence.

Hemond complained of neck and back pain and was taken to Central Maine Medical Center. Stevens suffered a laceration on his head, but refused medical treatment, police said.

Two blocks of Cedar Street from Lincoln Street to the Bernard Lown Peace Bridge remained closed along with the bridge for most of the day. The traffic light at the intersection of Cedar and Lincoln streets was knocked out along with power to much of the neighborhood until about 6 p.m. Monday.
