Cascade Bridge, LLC will widen Northeast 10th Avenue along the west side of Interstate 5 and build a 450-foot long bridge over Whipple Creek.
The two-lane steel and concrete bridge will span the gap that currently exists on Northeast 10th Avenue because of Whipple Creek. The bridge will be nearly 48 feet above Whipple Creek and will be built to last for 75 to 100 years.
Existing portions of Northeast 10th Avenue in this area are between 10 and 20 feet wide, with little or no shoulders.
The project will build one travel lane in each direction, along with 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.
Northeast 10th Avenue’s intersections with Northeast 154th Street and Northeast 164th Street will have conventional two-way stop signs, with Northeast 10th Avenue as the through street.
Construction on a related project, improving Northeast 10th Avenue between Northeast 149th Street and Northeast 154th Street (Capital Road Project 323322) , is scheduled to begin in 2020.

Clark County awarded a $14.62 million contract to Cascade Bridge, which submitted the lowest of the eight bids received for this project.
The contractor’s bid was $1.54 million lower than the county’s estimate of $16.16 million.
Cascade Bridge’s last major project for Clark County was replacing Fifth Plain Creek Bridge on Northeast 88th Street near Proebstel in 2015.
Construction started in mid-May 2017 and is scheduled to wrap up in fall 2018. There will be two to four months with little construction activity during the winter of 2017-2018 to allow time for newly graded and built-up soil, often called fill, to settle.
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. Local access will be maintained for residents, emergency vehicles and deliveries, although there may be occasional delays.
Adjacent residents will experience some rough road conditions, potential travel delays, noise, dust and vibration, all of which will be minimized as much as possible.
Purpose and need
Northeast 10th Avenue bridge and roadway improvements will:
- Improve traffic circulation by closing a gap in the existing transportation grid system, upgrading a roadway that does not meet current county road standards and improving access to recreational facilities.
- Enhance public health and safety by providing an alternate route for emergency responders, constructing safe bicycle and pedestrian facilities and creating a secondary access to the Clark County Fairgrounds.
- Support existing land uses and zoning, including providing an opportunity to extend utility lines across Whipple Creek, improving access to existing commercial and industrial properties and supporting Clark County's 20-year comprehensive plan.
Clark County already has completed two projects in advance of upcoming construction on Northeast 10th Avenue.
The Salmon Creek Interchange Project, a joint project between Clark County Public Works and the Washington Department of Transportation.
The $122.3 million state-county project included building a new interchange on Interstate 5 at Northeast 139th Street that opened in August 2014.
In addition, county roads were widened and improved on both sides of the freeway and the Salmon Creek Park & Ride lot was relocated for C-Tran buses.
The interchange project involved improving Northeast 10th Avenue, from Northeast Tenny Road to Northeast 141st Street. The county later built a separate project that improved Northeast 10th Avenue, from Northeast 141st Street to Northeast 149th Street.
