City Road between Haymarket Square and the Marco Polo Bridge will be down to one lane in each direction while final construction is completed as part of the Harbour Cleanup Project.
The traffic tieup will last until mid-September when the construction is expected to be complete. In the meantime, drivers are asked to use alternate routes.
Also, traffic will be reduced to one lane on Route 1 near Pocologan today and tomorrow. Crews will be working on the new Pocologan overpass.
