Motorists should expect delays between Algoma and High Streets where John Street becomes Oliver Road Monday.
Thunder Bay Hydro plans to work on a number of hydro lines in the area and will close off the road to traffic as that work takes place.
Thunder Bay Hydro officials say they also expect traffic will be impeded between Banning Street, Ontario Street and Secord Street.
Work begins at 10 a.m. and is expected to wrap up around 4 p.m.
