The purpose of the project is to replace the highway pavement that is in poor condition, and reconstruct the pedestrian access ramps and crosswalks so that they meet the current Americans with Disabilities Act (ADA) standards.
This project will grind and repave OR 99W from Hoffman Road to the City of Monmouth's southern boundary (milepost 62 to 63.9), and rebuild the roadway from Jackson Street south to Madrona Avenue. This reconstruction will reduce highway crosswalk cross slopes to meet ADA standards at crosswalks.

Cost and Funding
The project cost estimate is $14.8 million.
This project will make upgrades to existing curb ramps and sidewalks along the highway in the City of Monmouth to meet current ADA accessibility standards. The project will include striping bike lanes and installing landscaping between sidewalks and the highway from Church Street to Madrona Avenue. The project will also add a continuous two-way left turn lane between Church and Main Streets.
Typical Section of OR 99W
At the Main Street intersection:
- The curb radiuses will be increased to accommodate turning for larger vehicles. The vehicles designed for include a municipal bus on the west leg, and a WB-67 (semi-trailer with a 67’ wheel base) to and from the east.
- It is necessary to relocate and replace all of the traffic signals at the Main St. intersection to facilitate truck movement and improve operations at OR 99W at Main Street.
Other project elements include:
- Placing a waterproof membrane on the bridge over the Middle Fork of Ash Creek and adding new guardrail.
- Adding bioswales (large improved ditches) on the north and south sides of the city that will provide stormwater quality treatment for highway run-off.
