CLOSURE RESCHEDULED:
• The closure of the Kimball Bridge over Indian Creek has been rescheduled to early 2026. The City of Caldwell chose to reschedule the project to reduce impacts to the community during Winter Wonderland. Kimball Avenue will now remain open during the entirety of the event.
• Some prep work will occur in fall 2025 but will not have traffic impacts. Work includes removing the gazebo and vineyard near the intersection of Kimball Avenue and Blaine Street. The City of Caldwell has a separate project to replace the vineyard and add a gateway arch.
