Saint John drivers will face some delays Sunday as the 2019 Marathon by the Sea takes to the city streets.
One eastbound lane of the Harbour Bridge, along with the off-ramp to Chesley Drive and City Centre, will be closed from 6:30 a.m. to 3 p.m.
The speed limit in the other eastbound lane will be reduced to 50 kilometres per hour.
The run will begin at the Diamond Jubilee Cruise Terminal at 8 a.m. and follow a mapped route across the city before leading back to the terminal.
Police and traffic control personnel will be stationed across the bridge, and at major intersections and access points along the race route.
