What's Happening on U.S. 20 in July

4th of July Travel

As the holiday weekend approaches, travelers can expect to see increased congestion and delays on U.S 20 due to multiple construction projects in the area. Give yourself extra time when planning your trip. 

Stay alert for new traffic patterns or work zone staging areas that may remain in place. When approaching work zones, remember to slow down and drive cautiously for your safety and for the safety of our crews. All of the upcoming traffic pattern changes and detours are outlined below.

Roundabout at Old Bend-Redmond and U.S. 20 opens single lane

Roundabout construction of U.S. 20

Beginning on Monday, July 10, the new two-lane roundabout being constructed at U.S. 20 and Old Bend-Redmond Highway will open a single lane for travelers. The following steps will help you travel safely through a roundabout.

  • Slow down as you approach the roundabout. Look for signs to determine where your exit is located.
  • Traffic in the roundabout has the right-of-way. Before you enter the roundabout, you must yield to traffic inside and exiting the roundabout. Wait for a gap and merge into traffic. Be prepared to stop if necessary.
  • Once inside the roundabout, move around the circle until you reach your exit. Allow bicycles that have merged into traffic the full travel lane and don’t pass.
  • Indicate your plan to exit using your right turn signal. Watch for people in the crosswalk and be prepared to stop.

All work is dependent on weather conditions, and schedules are subject to change. Visit the U.S. 20: Tumalo – Cooley Road project website for more detailed information.
