Winnipeg firefighters doused flames Tuesday afternoon after an apparent culvert fire under Portage Avenue.
The blaze began just after 1:30 p.m. on Portage Avenue near Albany Street. Police closed the roadway for several blocks as thick, black plumes of smoke could be seen from opposite ends of the city.
A city engineer was reported to be attending the scene to ensure the structural integrity of Portage remained intact.
Meanwhile, Portage was closed between Lyle Street and Ferry Road.
No word on what caused the fire. No injuries were reported.
