Feb. 20, 2026:
Beginning Monday, March 2, 2026, road work is scheduled to begin on Interstate 90, near exit 101 in Wasta. The work includes the demolition and replacement of the bridge in the eastbound lanes of I-90 over Bull Creek, including approach grading and new asphalt surfacing. This is the second phase of the project. The first phase entailed replacing the bridge in the westbound lanes, which was completed in November 2025.
Traffic will be routed through the project in a two-way configuration in the westbound lanes for approximately three miles. The speed limit will be reduced on I-90 within the project limits, from 80 mph to 65 mph, 24 hours a day. The speed limit will be reduced to 45 mph when workers are present in the adjacent lanes.
Motorists should be prepared for suddenly slowing and stopped traffic. Travelers should be alert to construction workers and equipment adjacent to the roadway.
