2015 Dust Control Request Form


Benton County Public Works is constructing a roundabout at SW 53rd Street and West Hills Road to improve the intersection’s safety. The contractor scheduled to complete the work is R&R General Contractors. Here is the timeline:

May 1—Contractor moves equipment on-site and road construction begins. SW 53rd Street and West Hills Road will remain open to traffic, but may be limited to one lane.
May 18 — West Hills Road will be CLOSED to all through bicycle, pedestrian and car traffic except emergency vehicles. Please follow the posted Detour Routes.
July 24 — As long as everything goes according to schedule and the weather cooperates, the contractor will be complete with the roundabout and it will be operational in time for the Benton County Fair and Rodeo.
Oct. 30—Final construction and landscape work will be completed.

Here is information about how to navigate roundabouts for motorists, pedestrians, and bicyclists (Additional bicycle information coming soon)

March 10th Roundabout project notice

Roundabout FAQ's

Check out the mock roundabout, which is designed with the same dimensions as the one to be constructed, and try it out for yourself.  The mock roundabout will be accessible from either entrance to the Fairgrounds’ gravel parking lot located off of Reservoir Road. This mockup is the same size as what will be constructed this summer; however, it will be on gravel, which will ride differently than a finished paved surface. The roundabout will be available during daylight hours from March 9th thru March 31st.

SW 53rd Street and West Hills Road Intersection Improvements


Winter and Summer of 2015, Benton County will be widening and hard surfacing the remaining gravel section of Tampico Road.  Phase I is January 26th to February 28th and consists of the placement of asphalt grindings on the gravel section of Tampico Road between milepost 3.4 and the County line.  Phase II will start in August with additional grinding placement and a chipseal between Wiles Road and the County line to finish the project.

See how the County re-uses asphalt grindings to surface or restore base on County roadways.



South Fork Road is one lane of gravel in the east bound direction, at Mile Post 2.68, in South Benton County.   A large tree falling has impacted the roadway, gravel repairs have been made and final surfacing will occur when weather permits.


The county anticipates seeking grant funding from the state to replace the bridge. The next bridge grant cycle opens in April 2015. Repairs to the bridge would cost approximately $300,000 and would keep the bridge open for 5 to 10 years. Using the same amount as a match for Oregon Department of Transportation grant funding would enable enough money to replace the bridge, which would provide 60 to 75 years of use. The total cost of replacement is anticipated to be between $3 million and $4 million.

Nearby alternate route options are available by using Old River Road and Stow Pit Road. In the event of flooding on the alternative routes, in order to permit access in and out to area residents, the bridge will be reopened temporarily to passenger vehicle traffic as necessary.


The Union Pacific Railroad has retained a private contractor to remove rail and ties to complete their abandonment of the line from approximately Greenberry Road to Monroe and Dawson. Benton County doesn’t have direct involvement in this work but as the owner of the right of way, we will strive to keep adjacent property owners informed of the work. If you have any question please contact the Public Works Department at 541-766-6821 and ask for Laurel Byer, Laurie Starha, or Joe Mardis.
