A construction accident in Portland’s East Bayside neighborhood caused traffic lights to malfunction and knocked out power to more than 1,400 homes and businesses Monday afternoon.

Most of the affected Central Maine Power Co. customers had their power restored within an hour after the accident took place at 1:30 p.m.

John Carroll, a spokesman for CMP, said two utility poles on Anderson Street were damaged when a vehicle struck the poles. Portland police said they were informed that a dump truck had struck the poles, which had to be replaced. There is ongoing construction work in that section of Anderson Street.

Motorists reported that the traffic lights at Franklin Street and Marginal Way – a heavily used intersection by drivers getting on and off Interstate 295 – malfunctioned during the power outage, which affected 1,431 customers.

Carroll said CMP crews were able to restore power to 1,354 Bayside customers within an hour after the outage took place.

Carroll said it could take several more hours before power was restored to the remaining 77 customers.
