The full length of 122nd Avenue has various different land uses, traffic volumes, and needs for parking. PBOT's recommendations here are for changes to lane configurations that reflect these differences while balancing safety, access, and mobility.
SE Powell Boulevard to Foster Road
What's there now:
Two vehicle travel lanes in each direction, a center turn lane, and bicycle lanes in each direction that have no buffer between the vehicle lanes or parked cars.
Lower traffic volumes compared to northern segments of 122nd Avenue
Average daily vehicles ranging from 11,000 (near SE Foster Road) to 19,000 (near SE Powell Boulevard)
Land use is primarily residential, with higher utilization of parking spaces
Safe and marked crosswalks are far apart
Funding is available through Fixing our Streets 2 to repave and restripe 122nd Avenue between SE Powell Boulevard and SE Foster Road. Traffic analysis has determined that there will not be significant congestion or diversion resulting from this change. This funded project would lower the number of motor vehicle thru-lanes from two in each direction to one, allowing space for a center median, safer (and more frequent) crossings, and safer bike lanes and transit stops. We'd also improve the intersectionswhere SE 122nd Avenue crosses Holgate Boulevard and Foster Road.
PBOT is considering two possible designs for bike lanes as part of this change. The first option (pictured at left, below) would have bike lanes running along the curb, with parking between the bike lane and travel lane. This is referred to below as the "parking protected option." A second option (pictured at right, below) keeps parking along the curb, with the bike lanes between the parking lane and travel lane. This is referred to below as the "buffered option." The illustrations here also show new bus platforms, which would be installed as well, as funding allows.
NE Siskiyou Street to SE Powell Boulevard
What's there now:
- Two vehicle travel lanes in each direction, a center turn lane, and bicycle lanes in each direction that have no buffer between the vehicle lanes or parked cars.
- Higher traffic volume, between 20,000-25,000 vehicles per day on average
- Lower parking utilization
- Land use is a mix of businesses, services, and residential
- Contains two designated "Centers" in the Comprehensive Plan
In the 122nd Avenue Plan, PBOT recommends keeping the number of travel lanes the same, but removing on-street parking on both sides of the street. This would give more room for the existing bike lanes, allowing them to run along the curb, buffered or otherwise protected from people driving. Parking utilization is lower in this section of 122nd Avenue. There are more off-street parking options and more parking available along side streets.
This recommendation does not affect the current capacity for motor vehicles. It also makes it possible to convert lanes in the future, making them transit-only or allow parking at certain times. The plan also recommends we add bus platforms for better transit reliability. Learn more by going to Slide 9 - Transit stops. Finally, the plan recommends building a center median along this stretch of 122nd Avenue. This not only adds space for trees and landscaping, but helps us manage where vehicles can make left turns onto side streets or into driveways, keeping the road safer.
Freeway and railroad underpasses
What's there now:
Being a pedestrian or someone walking, rolling, or scooting on 122nd Avenue can be uncomfortable and challenging, especially where the road goes under the I-84 and the railroad bridge. On the east side of the street, bike lanes are right next to the motor vehicle lane, with no buffer or protection. In places, the sidewalks are narrow or not compliant with the Americans with Disabilities Act (ADA). On the west side of the street, pedestrians and people biking, rolling, or scooting must share a 6-foot sidewalk which is elevated in places and also goes through a tunnel.
To improve these conditions, the plan recommends:
- On the east side of 122nd Avenue: elevate the bike lane to the same height as the sidewalk This would create a shared, multiuse path between the I-84 ramp and NE Fremont Street.
- On the west side of 122nd Avenue: do more studies to see if a motor vehicle lane could be converted to a separate space for people biking.
