Travellers between Nipigon and White River no longer need to use a 562 km detour as the Jackfish River Bridge was reopened to traffic early Thursday evening.

The Ministry of Transportation had expected to reopen the bridge located 13 km east of Nipigon Thursday morning, but had to delay that to later in the day.

The road, which is part of the TransCanada Highway, was closed Tuesday "to facilitate emergency bridge repairs," according to a news release from the ministry.

During construction, "a structural deficiency" was discovered and that "affected the structural integrity of the existing bridge", according to MTO spokesperson Annemarie Piscopo. 

The re-opening was subject to an engineering review of the bridge.

The MTO says drivers will still encounter single-lane restrictions controlled by traffic lights while the Jackfish River bridge remains under construction.
