A tractor-trailer fire on I-90 in the Town of Portland kept firefighters busy and slowed down traffic on the highway for approximately four hours Tuesday afternoon. Westfield Fire responded to the area of milepost 480 in the eastbound lanes shortly before 12:15 PM on a report of a working fire near the rear wheels of the trailer. On arrival, crews found heavy fire conditions throughout the trailer. The department stated on its Facebook page that multiple tankers were called in to assist, and extinguishing the blaze was a challenge due to the contents of the trailer. While it was not clear what the contents of the trailer were, Westfield Fire says it was “mixed merchandise headed to a Home Depot.” Westfield received mutual aid from Ripley, East Dunkirk, Fredonia, North Lake, Chautauqua County Emergency Services, State Police and the New York Thruway Authority. According to NYSTA, traffic returned to normal shortly after 4:15 PM.
