A busy intersection in Old East Village will be closed for the next four days for sewer repairs.
Dundas Street at Rectory Street will be shut down in all directions as of Tuesday, the City of London said.
Detour routes have been set-up for drivers and cyclists, both of which are encouraged to find an alternative route in order to avoid the area altogether.
Signage is in place to guide pedestrians through the construction zone and London Transit buses are being rerouted.
Businesses in the area will remain open while road crews work.
The intersection is expected to reopen on Friday.
