Protected Bike Lanesin the City of Portland

Oregon Active Transportation Summit 2016

Lewis Wardrip PE

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)

SW Broadway – Clay St to Jackson St1/3 Mile 13,000 ADT 1-way 3 to 2 lanes

Currently have 2. miles 1.4 miles are in design

Accommodating lift buses

NE Cully Blvd – Prescott to EmersonApproximately ½ mile 4600 ADT

Complete road rebuild

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

Protected Bikeway Cross Section

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.

Basic design elements

Left turns out of travel laneCurb extension / possible swale

• 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

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

• 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

• Planters occasionally move• Sweeping is difficult• Painting a buffer between the stripes caused

some confusion and required a lot of maintenance

• Each mode needs its own surface material• Pedestrians want to be and should be at the

back of the sidewalk

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
