OR 8 Traffic and Pedestrian Improvements (Hillsboro and Forest Grove)

Design Phase

Region 1: Portland metro and Hood River County (Forest Grove, Hillsboro, Washington)

​​​​​​This safety improvement project in three locations on OR 8 in Hillsboro and Forest Grove includes new sidewalks, an enhanced pedestrian crosswalk, new lighting and upgraded traffic signals. 


Construction Impacts

​When construction begins, people can expect short-term lane and sidewalk closures.


​This project is currently in the design phase. Construction begins in 2025.



We are taking a system-wide approach to improving safety along OR 8. Several upcoming projects will upgrade crosswalks, intersections, sidewalks, curb ramps and lighting. This project is in three different locations on OR 8 in Hillsboro and Forest Grove. The three locations are:

Oregon 8 (SW Baseline Street) between Main Street and Dennis Avenue in Hillsboro: Fill in sidewalk gaps on the north side of SW Baseline Street between Main Street and Dennis Avenue, upgrade sidewalk curb ramps to meet ADA standards and replace the traffic signal at the SW Baseline Street and Main Street intersection. The new signal will be more visible and include pedestrian countdown timers, improving pedestrian safety by reducing the frequency of unsafe crossings.

Oregon 8 (SW Oak Street) and Armco Avenue in Hillsboro
: Add new lighting at this intersection to reduce nighttime crashes.

Oregon 8 (Pacific Avenue) and A&B Row in Forest Grove
: Build a new mid-block crosswalk with a pedestrian-activated beacon, also known as a Rectangular Rapid Flashing Beacon​, or RRFB. The crosswalk will also include a pedestrian refuge island halfway across. The location for this crosswalk was chosen because this section of OR 8 has long distances between crosswalks, and reduces the distance pedestrians must travel for a safe crossing. RRFBs are a critical part of our efforts to maintain a modern and safe transportation system.
