South Hillsboro project includes widening of Cornelius Pass Road
The city of Hillsboro is hoping it can find a balance between meeting the needs of today's drivers while also preparing for the massive influx of traffic when South Hillsboro homes begin to fill up.
The city has four projects in the works, with three additional projects in the pipeline, mostly centered around Southeast Tualatin Valley Highway. Hillsboro held an open house to discuss the upcoming projects with the community on Thursday, May 25, at Rosedale Elementary School.
"We're trying to get traffic capacity up now, in advance," said South Hillsboro Project Manager Gregg Snyder. "That way we can enjoy the benefits of it. It costs less when it's built now, and it enables South Hillsboro to grow and provide housing."
The largest project is the construction of a leg of the Willamette Water Supply pipeline, which will help the city handle expanded water needs in South Hillsboro.
The city is burying the pipeline before constructing any of the roads — even though the system won't be open for several years — to avoid ripping up roads once the additional water is needed.
One project already visible to drivers is work at the intersection of Southwest Cornelius Pass Road at TV Highway, where the city is adding dedicated left turn lanes and a new leg of the intersection that will cross the railroad tracks.
The city will be adding dedicated right turn lanes on TV Highway to speed up through traffic, and will also widen Southwest Cornelius Pass Road from two lanes to five lanes — two through lanes in each direction with a center turn lane and dedicated left turn lanes at certain intersections.
"That's really the last link in the chain from TV Highway up to Highway 26," Snyder said.
South of TV Highway, the city will initially build a five-lane layout for Cornelius Pass Road with the option to expand to seven lanes in the future.
Snyder said the city will hold another open house on transportation projects in late summer or early fall.
