Project Details

OR 99W Hoffman Road through the City of Monmouth

Construction Phase

Region 2: Willamette Valley and Northwest Oregon (Monmouth, Polk)


This project will repave OR 99W through the City of Monmouth, as well as reconstruct the pedestrian access ramps and crosswalks so they meet current Americans with Disabilities Act standards. ​​​​​​​


Impacts

Traffic Impact

DURING CONSTRUCTION:

  • Businesses access will be maintained during the project.

  • Pedestrian access will be maintained by using short detours as sidewalks are reconstructed.

  • Existing north and southbound vehicle lanes on the highway will stay open during the project. 

  • Expect nighttime single lane closures.

Except where noted, work hours are at night from 7 p.m. Sundays to 6 a.m. Fridays. During these times, there may be single-lane closures with flaggers safely directing traffic. There could be intermittent travel delays during construction work hours. All lanes will be open by the morning commute.

LOCAL ACCESS DETOUR (SUMMER 2019)

From July 8 through August 29, 2019 the center turn lane on Pacific Highway West/OR 99W approaching Main Street/OR 51, allowing us to rebuild half the roadway at a time, while allowing both northbound and southbound through traffic lanes to remain open.

Eastbound and westbound traffic on OR 99W wanting to turn onto Main Street will be redirected using detour signs to Hoffman Road during this stage of work. During this local detour, drivers on Main Street will still be able to turn north or south onto OR 99W at the signal, just like they do today.​​​​​​​​​

Construction Impacts

​DRAINPIPE INSTALLATION, SIDEWALK RESTORATION AND BRIDGE WORK (SUMMER 2019)

Both daytime and nighttime work will occur during June. Crews will perform daytime sidewalk upgrades and repairs on OR 99W between the Monmouth Police Station and Madrona Street. Some crosswalks will be closed temporarily, but will have signed alternative pedestrian routes. Please follow signs and use caution when crossing.

Crews will work on a retaining wall near the bridge over the middle fork of Ash Creek.

In June, the contractor will install stormwater infrastructure on OR 99W between Church Street and Jackson Street. At Jackson Street, for travelers heading east, the road will be closed to through traffic with local access only. A signed detour route will be in place via Church Street.​

Construction through June 2019 includes installation of sidewalk and curb ramps, underground pipes and stormwater infrastructure. The greatest impact from the project will occur in summer 2019, as crews grind and remove existing pavement and reconstruct the road.​

Meetings and Events

An in-person open house and an extended online open house were both held in April 2019.

About

​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

Additional Information

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.
