A tractor-trailer that hit a utility pole guide wire may have caused the pole to snap and lay across the road Tuesday morning, police said.

Shortly before 9:30 a.m. a pole on Allaire Road between Baileys Corner and New Bedford roads was laying across the road, blocking traffic.

The downed pole caused a power outage at Wall Intermediate School and the district's Special Services building, according to Superintendent Daniel Simon.

The police station also lost power and was running on a backup generator for about an hour, police said.

By about 10 a.m. the cause of the downed pole was unknown. No accident in the area had been reported, police said.

But police investigating the outage now believe a tractor-trailer caught a guide wire and snapped the pole. No one has been charged, according to an early afternoon release from Sgt. Erik Ertle.

The Allaire Road in the affected area will be closed until 5 p.m., Ertle said.
