Allumbaugh Street Construction to Start Soon

In December, the Ada County Highway District (ACHD) will begin construction on Allumbaugh Street between Franklin and Denton. The projects include roadway reconstruction, as well as safety and connectivity improvements for pedestrians and bicyclists. Work is expected to be complete fall 2027.*

*Construction schedules may change.

Construction will take place in two separate phases. Work from Franklin Road to Douglas Street is expected to begin as early as December 2026. Work from Douglas Street to Denton Street is expected to begin as early as spring 2027, after the first section is complete.

Construction Impacts

• Road closures and detours are expected during construction.
• Traffic lanes may shift, and flaggers will help direct traffic as work progresses.
• On-street parking may be limited in construction areas.
• Expect construction noise, dust, equipment backup alarms and ground vibration.
• Crews will work from 7 a.m. to 7 p.m. unless otherwise approved.
• The contractor will work with property owners to minimize impacts and maintain access

Construction on Allumbaugh Street will begin after Liberty Street is temporarily paved and reopened to two lanes of traffic.
