Portions of major roads on both sides of the border will be closed during part of Sunday to make way for the Niagara Falls International Marathon.
As many as 1,500 runners will step off from the Albright-Knox Art Gallery at 10 a.m., head west to the Peace Bridge and continue north along the Niagara Parkway in Ontario toward Table Rock in Niagara Falls, Ont.
Several shorter races, including a half-marathon, will take place on the Canadian side Sunday morning, as well.
Parts of the Niagara Parkway will be closed from Old Fort Erie to just above the falls starting at 6 a.m., and will reopen as the last participant runs past each adjoining intersection.
The northbound lanes of the Niagara Parkway from Upper Rapids Boulevard to Fraser Hill Street will be closed from 6 a.m. to approximately 5 p.m.; and the southbound lanes will be open and allow for two-way traffic to proceed.
Access to Dufferin Islands will be closed for the day but will remain open at Table Rock, and the nearby Falls and Floral Showhouse parking lots.
