Roadwork by London Hydro will create traffic hassles Tuesday and Wednesday this week, the city warned Monday in an advisory to Forest City drivers.

Motorists are being warned to expect delays when they are driving southbound on Wharncliffe Road where it intersects with Oxford Street from 9 a.m. to 3 p.m. on those two days.

Southbound traffic will be reduced to one through-lane, and turning left onto Oxford will not be allowed.

Westbound traffic along Oxford will likewise be reduced to one through lane. City hall says a police officer will be on hand at the intersection to help direct drivers.

London Hydro is closing the lanes to “relocate their infrastructure in preparation for the future widening of Western Road,” the advisory states.
