Important notice for drivers in Dubuque County:

Then Rd will be fully closed today, Wednesday, April 29, 2026, from approximately 8:00 AM to 5:00 PM (and possibly tomorrow, April 30) due to contractor drilling/boring work at the bridge over Curran Branch.

Details:

•  Location: Then Rd, approximately 500 feet south of the northern N Cascade Rd intersection

•  Affected section: 621 feet (full road closure at the bridge)

•  Duration: 1–2 days, daytime hours only (weather permitting)

•  Work: Bridge-related drilling project

The road will reopen outside of active work hours each day, but expect no through traffic during the daytime closure.
