Old Mill Bridge

The bridge sits at the bottom of a natural grade change, where the Humber River valley cuts through the west end of the city. The stone-faced arch dates to 1916. From the deck, or from the west-bank trail below, the valley shows itself in full: river, canopy on both banks, valley walls rising on either side. The Humber is wide enough here to feel like a separate landscape system rather than a gap between streets, and Old Mill Station sits a short walk from the crossing, which makes this one of the easiest thresholds in the guide to reach.

Context

The Old Mill Bridge was built in 1916 to a design by engineer Frank Barber, a concrete arch faced in stone so convincingly that it reads as a stone bridge. It replaced a truss crossing destroyed by an icy flood in March 1914. The Humber River watershed, managed by the Toronto and Region Conservation Authority, forms one of the major natural corridors linking Lake Ontario to the Oak Ridges Moraine.
