An annual fundraiser, which has given thousands to cancer research, is back in the nation’s capital on May 3.

It means that driving anywhere near downtown Ottawa might need extra planning this weekend. Between 6:00 a.m. and 2:00 p.m. several major roads will be closed or have lane reductions as a result of the CN Cycle for CHEO event.

Bikers will start and end at the Canadian War Museum and will cycle through downtown neighbourhoods and roadways, raising money for childhood and adolescent oncology care at the children’s hospital.

These are the roads expected to be impacted:

Kichi Zībī Mīkan

Island Park Drive

Champlain Bridge

Booth Street

Wellington Street

Portage Bridge

Elgin Street

Laurier Avenue

Queen Elizabeth Driveway

Prince of Wales Drive

Heron Road

Vincent Massey Park

Riverside Drive

Hogs Back Road

Colonel By Drive

Sussex Drive

Sir George-Étienne Cartier Parkway
