Advisory Shoulders & Bike Lanes 2023 Projects

Transportation
Upcoming
PBOT is planning to install advisory shoulders lanes in three locations in Portland in 2023. Advisory shoulders and bike lanes are a low-cost, low-impact treatment for narrow streets with lower volumes of traffic and speeds.
Advisory shoulders provide space on narrow roadways for people to walk, bike, and roll. People driving use the center lane in both directions and use the shoulder lane to pass each other. People walking, biking, and rolling have the right of way and people driving must yield the shoulder lane.
Construction in 2023 and 2024

UPDATE: What's happening now?

SW 40th Avenue from SW Huber to SW Wilbard streets was installed in April, 2024. View the plans here:

SW Talbot Street, SW Fairview Boulevard to SW Gaston Avenue is delayed while additional traffic engineering and pavement condition assessment takes place.

SE Ellis Street from SE 84th to SE 92nd avenue is delayed while additional pavement condition assessment and neighborhood outreach takes place.

How do advisory shoulders and bike lanes work?


Project background and description

PBOT will monitor and evaluate the advisory shoulder lane corridors before and after installation. The installation uses low-cost, non-permanent materials to allow for modifications as needed. 

Why advisory shoulders and bike lanes?

  • On shared roads, they provide space for people walking and using mobility devices where sidewalks don't exist.
  • The design provides more space between people biking, walking, and rolling and people driving.
  • They limit the likelihood of a bicyclist being hit by a parked car’s opening door, while still allowing for on-street parking.
  • They’re a great treatment for narrow streets with low vehicle traffic and low speeds.

What do we know about advisory shoulders and bike lane safety?

  • Studies from 11 US cities over 8 years and 60 million vehicle trips showed a 44% overall reduction in crashes compared to previously existing 2-lane configurations. (Mineta Institute. Safety Considerations for All Road Users on Edge Lane Roads. 2022)
  • Advisory lane designs typically lead to vehicles operating at slower speeds.
  • PBOT will only install advisory shoulder lanes on streets with low motor vehicle traffic and low speeds.
PBOT staff held a virtual open house to share information and gain feedback about advisory shoulder and bike lanes.

Public Involvement Opportunities & Past Outreach

Public notification for 2023 advisory shoulder lane are projects were mailed in spring 2023.

PBOT planned to install three advisory shoulder projects in 2023 including: 

Advisory shoulders and bike lanes were installed in three locations in 2022: 

  • NE San Rafael Street between 111th and 122nd avenues.
  • NE 43rd Avenue between NE Tillamook Street and NE Sandy Boulevard.
  • NE 53rd Avenue between NE Hoyt and NE Irving streets.

Frequently Asked Questions

What qualifies as a "low traffic street" for advisory shoulders or bike lanes?

Federal Highway Administration guidance recommends streets that average less than 4,000 vehicles per day. PBOT's constructed or proposed advisory shoulder and bike lane project streets all operate with less than 4,000 vehicles per day, with most in the 1,500 to 3,000 average daily traffic range. The last 10 years of collected traffic data is available on our publicly accessible webmap.

What traffic studies have you done on the existing or proposed projects? 

Each project will have before and after traffic impact analysis completed. Those studies include collecting and interpreting vehicle speeds and volume data, evaluating crashes and crash risk, and conducting transportation network analysis for potential benefits and issues that could arise.

For example, PBOT has conducted 81 traffic counts (and 34 since 2015) on NE San Rafael Street between NE 111th and NE 148th Avenues. Depending on the street's operating conditions and the length of the proposed project, the number of traffic studies will vary.

Will advisory lanes or shoulders lead to more crashes?

In other cities, the advisory lane design led to equal or lower speeds, and equal or reduced crash rates. The Mineta report (2021) studied 13 US advisory lane sites and estimated a reduction in crashes of 7 – 44%, with zero head-on crashes.​ The Alta report (2017) studied 10 advisory lane sites in US/Canada. No significant issue with crashes has been reported in any installation. Some reported improvement.​ PBOT intends to post each advisory shoulder or lane at 20 mph.​

Why build advisory lanes or shoulders where there are few people biking?

Portland city goals call for creating conditions that encourage and allow for increased pedestrian, bicycle, and transit use as alternatives to driving. PBOT experience has been that creating good conditions for biking results in more biking and less driving. PBOT understands that not everybody is going to ride a bike. Even those who do ride bikes don't do so for every trip. All of our advisory shoulder or bike lane designs continue to accommodate two-way traffic for automobiles. These projects improve mobility for more people and modes of traffic.

Why not build sidewalks instead of advisory shoulders or protected bike lanes instead of advisory bike lanes?

PBOT's goals are to build to sidewalks and better bike lanes on many miles of city streets. However, many of those streets require significant financial investments to build new sidewalks or protected bike lanes. In the meantime, advisory lanes and shoulders can provide increased mobility and better spaces for walking, biking, and rolling.

What if two cars collide, who will be at fault?  

Traffic is expected to yield to oncoming traffic, This website has more information from the Oregon Revised Statutes (oregon.public.law/statutes/ors_811.300). If you have specific questions around the law, it is best to contact legal consultants.

Do advisory lanes violate the Oregon law that prohibits driving in bicycle lanes (ORS 811.440)?

ORS 811.300 addresses the need for drivers to move right for oncoming traffic. The duty of care that all drivers must take in ensuring that there are not cyclists in the bike lane before entering into that bike lane, assuming they needed to avoid oncoming vehicular traffic, would also apply. These are concomitant duties; they are not necessarily exclusive of one another. This specific design is consistent with advisory bike lane design in the US, Canada, and other parts of the world, and approved by the Federal Highway Administration. PBOT has no indication that the design will increase the risk of crashes, with published research concluding it typically reduces crash risk. If you have specific questions around the law, it is best to contact legal consultants.


Information for screen reader users

PBOT understands that the links above are not screen reader accessible and we are working towards a permanent solution.  Due to the complexity of the information the map provides and the currently available map platforms at the city, we ask for your patience while we work on a technology-based solution.  As we work toward providing that level of accessibility, please contact Scott Cohen at 503-823-5345 to reach PBOT staff who can assist you to get the data you need from the map.   You can also contact PBOT’s ADA Coordinator at Lisa.Strader@portlandoregon.gov or at 503-823-5703. Thank you for your understanding and patience.
