Expect intermittent delays and travel reduced to one lane each direction

Work on the U.S. 30 Snake River Bridge in Ontario is scheduled to begin Monday, April 4. We expect work on this bridge to be completed by the end of September.

During construction, you can expect to see the following:

  • Intermittent delays of up to 20 minutes.
  • You may see occasional flaggers to accommodate equipment in the work zone and for other necessary tasks.
  • Traffic in each direction will be reduced to one lane at all times starting April 11.

Motorists are encouraged to use alternate routes to avoid congestion.

Bicyclists and pedestrians, including those with disabilities, will be allowed access through the work zone at all times.

The project contractor, Hamilton Construction Company, from Springfield, Oregon, will replace bridge joints, repair concrete girders, replace pavement, construct new curb ramp on the northwest (Oregon) side of bridge and retrofit existing rail to meet standards.

Crews are scheduled to work Monday through Friday, 7 a.m. to 5 p.m. But there may be some work on weekends and nights.
