Viaduct demolition tracker

Tracking viaduct demolition

The interactive map below shows current active construction areas and estimated dates for each segment (frame) of the viaduct. The start and end dates shown include time for setting up fences, preparing the site, active demolition, and restoring the site to its previous condition.

Work start dates more than 14 days ahead are estimates and subject to change.
