Calgary has a winter night market and it lives where no one expected. Tonight a once-windswept underpass beneath the 4th Avenue Flyover opened as the Subzero Night Market, with radiant-heated walkways, soft projection art, and compact vendor pods serving hot food, repairs, and crafts. The pilot runs evenings Wednesday through Sunday.

What we saw

Within minutes of opening, thin steam curled from the heated lanes as visitors sampled skewers and cocoa. A cobbler repaired winter boots at a stand-up bench. A makers table engraved initials on metal tags while ambient projections drifted over the girders.

Why it matters

Downtown evenings have struggled for foot traffic. Re-programming winter-proof spaces like this underpass offers a practical way to extend street life without waiting for permanent construction.

Whats next

Organizers will track warmth, light spill, and sound against set thresholds during cold snaps. A weekend dawn market focused on coffee and baked goods is slated next.
