Correction 10/5: Unfortunately, an earlier version of this post was based on inaccurate data. As explained in the comments by Portland Bicycle Planning Coordinator Roger Geller (and first noticed by reader Psyfalcon), the Hawthorne counter failed to capture eastbound bike data from Sept. 9 through the end of the month. This problem wasn’t noted on the city’s website but we should have noticed the east/west discrepancy and checked with the city before running this story.
This means it’s likely that the Tilikum has boosted total bike traffic across the Willamette, but that Hawthorne bike traffic hasn’t dropped by anywhere close to one-third. It’ll take several weeks to learn the truth. In the meantime, we regret the error. The original (incorrect) version of the post follows.
