Improvements to Roy Rogers, Tualatin-Sherwood roads underway
Road improvements along Southwest Tualatin-Sherwood Road continue this month in Sherwood as Washington County's Department of Land Use and Transportation gears up for work along the major arterial road between Langer Farms Parkway and Teton Avenue.
The latest planned project incudes the widening of Tualatin-Sherwood Road to five lanes — two lanes in each direction plus a center turn lane — between the two cross streets. In addition, multi-use paths for cyclists and pedestrians will be built. Storm drains and street lights will be added as well.
Years in the making as traffic has progressively worsened on the road between Tualatin and Sherwood, this roadwork won't be a quick fix, Washington County officials acknowledge. After beginning this month, construction is expected to continue through fall 2025.
This project will connect to the Tualatin-Sherwood Road and Highway 99W intersection improvement project already underway.
Transportation officials say new construction there will improve traffic flows and provide a safer roadway for motorists, pedestrians and bicyclists traveling along Southwest Roy Rogers Road from Borchers Drive to Langer Farms Parkway.
Roy Rogers Road is effectively a continuation of Tualatin-Sherwood Road on the west side of Highway 99W, which is signed locally as Southwest Pacific Highway.
Roy Rogers Road connects Sherwood in the south with Beaverton's South Cooper Mountain area and Tigard's River Terrace neighborhood in the north.
Improvements include widening Tualatin-Sherwood Road in order to add two westbound through-lanes. In addition, plans call for widening Tualatin-Sherwood Road, east of Langer Farms Parkway, to add a second eastbound through-lane beyond the Langer Farms intersection.
At the same time, the Highway 99W intersection will be improved by adding two eastbound-to-northbound dual left-turn lanes along with adding a westbound through-lane, an eastbound-to southbound dedicated right-turn lane and a southbound-to-westbound dedicated right-turn lane.
Construction plans also call for widening Highway 99W by adding a northbound lane from Tualatin-Sherwood Road to Langer Farms Parkway. Bike lanes on both sides of Tualatin-Sherwood Road, between Borchers Drive and Langer Farms Parkway, are planned as well.
Construction on the roadways continues. The county advised last week that motorists traveling the route should expect intermittent lane closure on weekdays from 7 p.m. to 5 a.m. and 9 a.m. to 4 p.m.
Overall construction for the Tualatin-Sherwood Road and Highway 99W project is expected to be completed by spring 2024.
Improvements are also being made along Roy Rogers Road between Chicken Creek — which runs about 300 feet north of Southwest Cedarview Way — and Borchers Drive.
That project also will include five lanes — again, two lanes in each direction plus a center turn lane — between the two roadways, as well as multi-use paths, storm drainage improvements and street lights. Crews will also erect sound walls as part of the project to reduce road noise in the nearby neighborhood.
The Roy Rogers Road project is funded through the county's transportation development tax, a tax imposed on most new development.
The Willamette Water Supply System, a partnership between Tualatin Valley Water District and the cities of Hillsboro and Beaverton to build a seismically resilient regional water supply system in Washington County, is also involved.
The scope of the work on Roy Rogers Road includes a 66-inch drinking water pipeline that is being installed in conjunction with road improvements.
The overall pipeline project calls for the construction of an intake line that originates on the Willamette River in Wilsonville.
Construction on the Borchers Drive to Chicken Creek project is also getting underway this month and is expected to be completed in fall 2024.
