Highway 144 was closed for about eight hours on Saturday following a 'serious' two-vehicle collision in the Greater Sudbury community of Cartier, according to the Ontario Provincial Police.
OPP first reported the crash on social media at about 1:44 p.m. on Saturday, stating that all lanes were blocked just south of Cartier.
The Ontario Ministry of Transportation's 511 Traveller Information Service confirmed the closure of the roadway between Windy Lake Provincial Park Road and Cartier's West Entrance shortly after 2 p.m.
The collision was 'cleared' by late evening, with the Ontario 511 stating that Highway 144 had reopened July 5 at 9:55 p.m. on X, formerly Twitter, and OPP confirming the roadway was reopened only minutes later, on its social media pages.
'Highway 144 has now fully re-opened. Thank you for your patience,' police wrote.
Police had advised motorists to use Old Cartier Road, also known as Old Highway 544, as a detour when possible, warning that the closure could last several hours.
Authorities have not released any details about injuries, the types of vehicles involved, the cause of the crash or if any charges are pending as a result.
CTV News has reached out to authorities for more information on the crash, but those messages have not yet been returned.
