U.S. 218 lane closures begin Monday, July 6 in Waterloo: driver checklist

Drivers using U.S. 218 through Waterloo should plan for slower travel starting Monday, July 6, 2026. The Iowa Department of Transportation says the corridor will shift to continuous single-lane closures in both directions for hot-mix asphalt resurfacing, with at least one lane open in each direction.

What’s changing on U.S. 218

Iowa DOT describes the project as continuous single-lane closures (instead of fully closing the road) while crews resurface the highway with hot-mix asphalt. The notice also says some work will happen at night, when traffic will be reduced to one lane in each direction.

Where the work is in Waterloo

The lane closure limits run from the west U.S. 63 interchange to the Cedar River bridge. Drivers traveling between west Waterloo and the Cedar River/downtown area should expect the most consistent work-zone impacts on that stretch.

When it will run

Iowa DOT says the closures are expected to continue through mid-October, weather permitting. Because construction schedules can change, residents and businesses should treat the end date as an estimate.

What drivers should expect

Even with one lane remaining open in each direction, continuous single-lane work zones can mean:

• Slower travel through the work limits
• Delays, especially during peak commute times and delivery windows
• More variability in drive times from day to day

KILJ Radio also urged travelers to allow extra time and check for updates during the project period.

Get updates: set up Iowa 511 alerts

For day-to-day traveler information and updates, Iowa DOT points drivers to Iowa 511. The Iowa 511 help page explains how to create a personalized 511 account and schedule email/text alerts for your favorite routes, places, and areas.

Quick practical checklist:

• Plan extra time for U.S. 218 trips through the Waterloo work limits.
• Check 511 before you leave, especially on days when overnight work could affect morning conditions.
• For businesses and deliveries: coordinate schedules so you’re not stacking appointments behind the single-lane restrictions.
