A power outage at Tunney's Pasture is causing rush hour traffic delays on the Transitway and even stretching to the Parkdale Avenue ramp to Highway 417.

Hydro Ottawa says a truck collided into a street pole taking down power lines at Parkdale Avenue and Scott Street.

Almost 9 thousand customers are affected in an area stretching from Churchill Avenue to Preston Street.

Hydro Ottawa hopes to have power restored by 5 p.m.

OC Transpo says buses will be on detour routes in each direction.
