Project Description

Within City limits Main Avenue has sidewalks, curbs, and sufficient lane width (35-feet) to safely accommodate bicycles and vehicles. Beyond the City limits, Main narrows down to a 22-foot wide, two-lane rural road. There is currently no safe walking path along Main Avenue forcing pedestrians visiting the Carty Unit and Refuge, to walk in the vehicle travel lane. Narrow shoulders, missing sidewalks and roadside drainage ditches regularly force pedestrians into the vehicle lane which then forces on-coming vehicles over the center line to avoid pedestrians. Hikers, runners, cyclists and families with baby strollers are regularly observed along Main between the City and Refuge. Vehicle speeds average 50 mph in this area according to county data, creating a significant risk to pedestrians in the vehicle travel lane.

This project would create sate intermodal access between the City and Carty Unit for visitors to the refuge. Additionally, the trail would accommodate safe non-motorized access for nearby residents seeking amenities and services within the City less than 1 mile south.


Construct new multi-modal bicycle and pedestrian facility from existing sidewalk near the Ridgefield city limits, approximately 2,200 feet north to the Carty Unit Headquarters of the Ridgefield National Wildlife Refuge.

Project Partners

Ridgefield Wildlife Refuge, City of Ridgefield, Clark County, and the Federal Highway Administration.

Tentative Preliminary Scope of Work

(to be confirmed through the Public Involvement Project and verified through engineering and resource studies)

This project will construct approximately 2,200 feet of missing sidewalk, addressing safety issues by moving pedestrians from the vehicle travel lane to a dedicated, separate sidewalk/trail. This work will include:

  • Construction of approximately 0.40 miles of attached and detached 6 to 10 foot wide paved sidewalk from end of existing sidewalk near Ridgefield city limits to the northern end of the refuge frontage near NE 291st Street.
  • Significant excavation of embankments to the north and extensive fill along the south portion of the proposed sidewalk, together totaling approximately 11,300 cubic yards of material.
  • A new crossing of Gee Creek, will replace the existing undersized culvert on Main Avenue, reducing flooding risk to public and private lands ,and removing a current barrier to fish passage.
