VANCOUVER — Construction will start this week on a major project to widen, connect and improve Northeast 10th Avenue, including building a bridge over Whipple Creek.
Cascade Bridge, LLC of Vancouver will improve Northeast 10th Avenue from Northeast 154th Street north to Northeast 164th Street. The project will add one travel lane in each direction, a center turn lane, bicycle lanes, sidewalks and facilities to collect and treat polluted storm runoff. Water and sanitary sewer lines will be constructed as part of the project.
A new two-lane steel and concrete bridge will span the current gap at Whipple Creek. The bridge will be nearly 48 feet above Whipple Creek and will be built to last 75-100 years.
Northeast 10th Avenue will be closed to most traffic between Northeast 154th Street and Northeast 164th Street on both sides of the Whipple Creek canyon. Area residents, emergency vehicles and deliveries will have access, although drivers might encounter delays.
During winter 2017-2018, construction will slow for two to four months while newly graded and built-up soil, often called fill, settles.
Clark County awarded a $14.62 million contract to Cascade Bridge, which submitted the lowest of the eight bids received for the project. The contractor’s bid was $1.54 million lower than the county’s $16.16 million estimate.
Construction is expected to wrap in fall 2018. A related project, improving Northeast 10th Avenue from Northeast 149th Street to Northeast 154th Street, is scheduled to begin in 2020.
