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.

Typical Section of OR 99W

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.
