Bridges near Gaston to be replaced
Washington County road crews are preparing to take out three small bridges in the rural Gaston area and replace them with more durable concrete spans.
The trio of bridges set to be replaced are on Southwest Gaston Road, just west of Southwest Spring Hill Road, and Northwest Mt. Richmond Road, where a pair of bridges in between Northwest Patton Valley and South roads will be replaced.
Gaston Road crosses Wapato Creek east of Gaston city limits, before it intersects Spring Hill Road. That timber bridge is nearing the end of its expected lifespan, says the Washington County Department of Land Use & Transportation, and so it will be replaced next summer.
The bridge replacement is expected to close Gaston Road west of Spring Hill Road for about four months, starting in July. Spring Hill Road and Tualatin Valley Highway, also signed as Highway 47, will serve as a detour around the closure.
For ease of construction, the Mt. Richmond Road bridge work is being staged in two parts. The northern bridge over the Tualatin River will be replaced starting in December. In the second phase of the project, the southern bridge over a fork of the Tualatin will be replaced starting in July.
The two-stage Mt. Richmond Road project is set to wrap up by the end of October.
The Gaston Road bridge replacement is estimated at about $1.4 million. It's being paid for through the county's Major Streets Transportation Improvement Program, or MSTIP.
The county is paying for the Mt. Richmond Road project from its road fund, with the Oregon Department of Transportation also chipping in for the bridge work.
An open house has been scheduled in Gaston for area residents to learn more about the projects and how they will be affected. It will be held from 5 to 7 p.m. Thursday, Oct. 10, at Gaston City Hall, 116 Front St.
The meeting will have a casual, drop-in format. No formal presentation is scheduled. Attendees are invited to speak with project staff, ask questions and provide feedback.
Sign language and spoken interpretation are available by special request. Anyone needing one of these services is asked to call 503-846-7822 at least 48 hours prior to the open house.
