- WSDOT plans to advertise the project for construction in spring 2010.
- The current design (pdf 148kb) includes:
-
Widen SR 14 from two lanes to four lanes from the end of the West Camas Slough Bridge to Union Street (SR 500).
-
Construct a new bridge on the east end of Lady Island.
-
Build a split-diamond interchange at Union Street and 2nd Street.
-
Install median barrier on SR 14 throughout the length of the project.
Overview
WSDOT is working with the cities of Camas and Washougal, the Port of Camas-Washougal, Clark County and the Southwest Washington Regional Transportation Council to make transportation improvements to State Route 14 between the NW 6th Avenue interchange in Camas and 6th Street in Washougal.
This project will widen SR 14 from two lanes to four lanes from the end of the West Camas Slough Bridge to Union Street (SR 500). Included in the project will be construction of a new bridge, parallel to the existing bridge on the east end of Lady Island and construction of a split-diamond interchange at Union Street and 2nd Street. This project will improve safety in the corridor, increase capacity and reduce travel time on SR 14 to accommodate residential, commercial and industrial growth.
Why is WSDOT
building this project?
SR 14 functions as an urban freeway that provides access between Camas, Washougal and Vancouver, and also serves as a state route connecting southwest Washington to south-central and southeast Washington. SR 14 in the Camas-Washougal area is a two-lane high-speed state highway with multiple signalized and unsignalized intersections.
This section of SR 14 has a continuous occurrence of severe accidents, occurring primarily at the intersections. As traffic volumes continue to increase on this corridor, higher demand will be placed on SR 14. This project will accommodate this demand while improving safety and reducing travel times along SR 14.
What has changed in the design of this project?
Due to escalating costs associated with rising material prices and new seismic design standards, WSDOT revised the design of this project in 2008 to fit within the $57 million budgeted for the project.
Originally, the 1,037 foot long West Camas Slough Bridge was planned to be widened from two lanes to four. Instead of widening the bridge, WSDOT will improve on the structure's current safety measures by replacing the existing bridge rail and adding a median barrier down the center of the bridge.
The half interchange at Union Street has been redesigned as a split-diamond interchange at Union and 2nd Streets. The addition of a bridge over SR 14 at 2nd Street will improve traffic circulation by giving drivers more options when crossing SR 14 from either direction. It will also reduce the number of traffic conflict points on SR 14.
Other features of the previous design, including median barrier on SR 14 for the length of the project and a new frontage road south of SR 14, are included in the current design.
Our Partners
The Port of Camas/Washougal, the cities of Camas and Washougal, and Clark County have all played significant roles in obtaining funding for this project and they will continue to provide input throughout its development.
The End Result
This project will widen SR 14 from two lanes to four lanes from 6th Avenue to Union Street (SR 500). The addition of median barrier will safely divide east bound traffic and west bound traffic between NW 6th Avenue in Clark County and 6th Street in Washougal. Also included in the project will be the construction of a new bridge over the East end of Lady Island, widening the shoulders and replacing the existing bridge rail on the West Camas Slough Bridge. In addition, this project will build a new split diamond interchange at Union Street and 2nd Street. This project will improve safety in the corridor, increase capacity and reduce travel time on SR 14 to accommodate residential, commercial and industrial growth.
When complete, this section of highway will better serve current and future commuter traffic demands and better accommodate the movement of goods and services.
Project Benefits
- Safety: This project will provide safer access to SR 14, eliminate crossover accidents and reduce rear end accidents by consolidating access points on SR 14, installing median barrier, and by building a split diamond interchange in the vicinity of SR 14/SR 500 (Union Street) and 2nd Street.
- Congestion relief: The added capacity created as a result of this project will reduce delays to the traveling public.
- Economic: This project will accommodate future residential, commercial and industrial growth in the corridor area.
