Roundtable discussion on the planning and designing of protected bike lanes, design techniques, and stakeholder challenges. Presenter: Lewis Wardrip

1. Protected Bike Lanes
in the City of Portland
Oregon Active Transportation Summit
2016
Lewis Wardrip PE

2. Portland currently has 2.5 miles of protected bike
lanes.
We are currently in design for another 1.4 miles.
• SW Broadway (striping)
• NE Cully (road reconstruct)
• SW Multnomah Blvd (road reconstruct)
• NE Multnomah St (striping and planters)
• SW Moody Ave (road reconstruct)
• Future NE 47th Ave (road reconstruct)

3. SW Broadway – Clay St to Jackson St
1/3 Mile 13,000 ADT 1-way 3 to 2 lanes
Currently have 2. miles
1.4 miles are in design

4. No Right Turning Traffic
PSU

5. Cycle track

6. SW Broadway parking-protected bike lane

7. Accommodating lift buses

8. NE Cully Blvd – Prescott to Emerson
Approximately ½ mile 4600 ADT
Complete road rebuild

9. 6’ sidewalk, 4’ planter, 8.5’ cycle track

10. Protected Bikeway Cross Section

11. Cycle track is higher than the roadway and
lower than the sidewalk.
• A mountable curb delineates the
bike zone from the parking zone
• Sidewalk curb allows for street
sweeping of cycle track
• Removes responsibility from
adjacent property owner to
maintain cycle track.

12. Basic design elements
Left turns out of travel lane
Curb extension / possible swale
Grade-separated bikeway

13. NE Cully protected bike lane at an
intersection

14. White striping on concrete
2’
5’
1’

15. • Challenging design for storm water
• White striping has no contrast on fresh (white)
concrete
• No parking upstream of driveways and
intersections because of right turns

16. SW Multnomah Blvd 2300 block to 31st
.4 Miles 19,000 ADT

17. SW Multnomah Before

18. SW Multmomah After

19. • Shared bike and pedestrian on south side is
frustrating for some users
• The parking area needs to be well marked or
drivers will park in the bike lane

20. NE Multnomah Wheeler to 16th
.8 Miles 10,000 ADT
Lloyd

21. NE Multnomah
Before (5 lanes)

22. NE Multnomah After (3 lanes)

23. NE Multnomah barrier-protected cycle track

25. 25

26. • Planters occasionally move
• Sweeping is difficult
• Painting a buffer between the stripes caused
some confusion and required a lot of
maintenance

27. SW Moody Ave - Sheridan to Gibbs
Two way raised bikeway
2250’

28. SW Moody After (phase 1)

29. Phase 2

30. SW Moody After (phase 3)

31. Streetcar platform

32. Intersection

33. Contrast pavement marking

34. • Each mode needs its own surface material
• Pedestrians want to be and should be at the
back of the sidewalk

35. NE 47th - Columbia Blvd to Cornfoot Rd
.5 miles 8500 ADT

36. NE 47th Proposed Cross Section
24’ to 26’
Curb to Curb

37. Lots of driveways

38. The Future
• Directive to always strive to provide protected
bike lanes
• In a physically and monetarily constrained
environment providing protected bike lanes
can be challenging
• Our experience - protected bike lane design
requires creativity
