The Ada County Highway District is installing a new traffic signal and dedicated left-turn lanes at McMillan and McDermott in Meridian, while a stretch of McMillan Road farther west is fully closed for sewer work tied to the Can Ada Lift Station project. At McDermott, McMillan Road remains open with lane restrictions.
Why it matters
For Meridian households driving or walking along McMillan Road, the work changes daily commutes and school runs while it is underway. The city says the Can Ada Lift Station infrastructure is needed to accommodate growth in the area, which is why the sewer work is moving forward now.
The intersection work includes a new traffic signal and dedicated left-turn lanes, with McMillan Road open but lane-restricted at McDermott. A separate stretch of McMillan Road is completely closed for the third and final phase of the Can Ada Lift Station sewer project.
The players
Ada County Highway District
The regional highway agency that maintains roads across Ada County, including the McMillan and McDermott intersection upgrades.
City of Meridian
The city government responsible for the Can Ada Lift Station sewer project that supports growth in the area.
The details
The Ada County Highway District is improving pedestrian safety at McMillan and McDermott by installing a new traffic signal and adding dedicated left-turn lanes. Where a crosswalk at the intersection was previously grass and weeds, the upgraded crossing is part of the safety work. Sewer work farther west is the third and final phase of the Can Ada Lift Station project, which requires a full road closure.
Timeline
Early November 2026: McMillan and McDermott intersection improvements are expected to be complete.
December 4, 2026: The final phase of the Can Ada Lift Station project is expected to wrap up.
The Home Front
Two neighborhoods have been built in this area in the roughly two years since the Roberts moved in, and the city ties the Can Ada Lift Station directly to that growth. Infrastructure like this is typically how Meridian's expanding neighborhoods get the sewer and road capacity they depend on.
If your commute or school route uses McMillan Road, plan extra time and expect lane restrictions at McDermott and a full closure farther west until the project wraps up. Check the Ada County Highway District's project notices before driving the corridor, especially in the weeks before the early-November and December completion targets.
The takeaway
Growth-driven sewer and road work can disrupt a corridor for months, so it helps to set your route plans early. Keep the early-November and December 4 completion dates on your calendar and check local project notices before the next major change.
What happens next
The McMillan and McDermott intersection improvements are expected to be complete in early November 2026, and the Can Ada Lift Station final phase is expected to wrap up by December 4, 2026.
