Nicholas Street traffic changes, multiple events may pose traffic impacts this Sunday, April 24

Nicholas Street traffic changes along with road closures and detours for multiple events may pose traffic impacts to area motorists this Sunday.


Beginning on Sunday, April 24, Nicholas Street northbound between Highway 417 and Laurier Avenue will be converted to one general traffic lane and one bus-only lane. Buses and general traffic will share both southbound lanes on Nicholas Street, with a reserved bus lane beginning at the Highway 417 eastbound on-ramp. This change will be in effect at all times.


Motorists are advised to use alternative exits and entrances on Highway 417, give priority to transit vehicles and respect the reserved bus lane signs and markings.


The Nicholas bus-only lane replaces the Transitway from Laurier Avenue to Lees Avenue, which will permanently close on Sunday for the construction of the O-Train Confederation Line.


Queen Street will also see traffic changes due to construction, reducing it to one eastbound-only lane from Bay to Metcalfe streets.


Along with these major roadway changes, several events are occurring on Sunday that will result in road closures and detours.  These include:

Armenian Genocide Anniversary demonstration march will take place from 2 to 3:30 p.m., and will involve intermittent road closures on the following route: east on Wellington and Rideau streets, north on Cobourg Street and east on Heney Street.

Alive to Strive Run takes place from 8 a.m. to 1 p.m., closing Hog’s Back from Prince of Wales Drive to Riverside Drive.

MS Walk takes place around the Lebreton Flats (War Museum) area from 8 a.m. to 2 p.m., resulting in intermittent closures, traffic disruptions and lane closures on: Wellington Street, Sir John A. Macdonald Parkway and Parkdale Avenue.

Carleton University Student Move-out is from 8 a.m. to noon, and the Colonel By Drive entrance will be closed. All traffic must enter and exit at Bronson Avenue.

All residents are encouraged to plan out alternate routes or choose alternate forms of transportations, like cycling.
