HSR detours on Routes 1, 4, 10 and 41 are posted to run into December, with downtown crane work rerouting more buses

Main and Ottawa: Routes 1, 10 and 41

The City's HSR schedules and detours page lists a detour of Routes 1/1A King, 10 B-Line and 41 Mohawk because of construction at Main Street East and Ottawa Street North, with operating dates of Monday, August 17 to Monday, December 7, 2026. The page notes that the dates depend on construction progress and points to hamilton.ca/MainOttawa for the latest information. Our earlier story on the intersection closure said it was expected to last about four months; the December 7 date comes from HSR's detour listing.

• Route 1/1A King: westbound buses turn onto Edgemont Street North, Dunsmure Road and King Street East; eastbound buses use Ottawa Street South, Maple Avenue and Edgemont Street South.
• Route 10 B-Line: runs via Kenilworth Avenue North, Cannon Street East and Gage Avenue North, with temporary stops at Main at Crosthwaite, Cannon at Ottawa and Gage at King.
• Route 41 Mohawk: runs via Gage Avenue North and Cannon Street East, with several Ottawa Street stops near the intersection out of service.
