The sinkhole on Mainstreet will be causing some traffic woes for motorists Tuesday.

While crews fix the sinkhole, southbound traffic will be detoured at Ominica St, and northbound traffic will be detoured at High St.

Barricades and signage are in place, and pedestrian access and businesses will remain unaffected.

Additional bus stops will be added to the northwest and northeast corners of 1st Avenue Northwest and Ominica Street West. Transfer points for all transit routes will be relocated to 1st Avenue Northwest between River Street West and High Street West in front of Mosaic Place.

Buses outbound to Route 1 - Athabasca East, Route 2 - Athabasca West / Thatcher, and Route 3 - Sunningdale will board on the East side of the street, and the bus outbound to Route 4 - Westmount will board on the West side of the street.

It is believed the sinkhole was created due to conditions left by a previous water main break, and repairs are expected to be completed Wednesday.
