What are your sources? From 2013: > Leading up to the construction and just afterwards NE 65th St performed very similar to both controls, however two quarters after the project was finished NE 65th St experienced a 350% increase in sales index, followed by another jump to 400% sales index the following quarter.[1]

From 2020 [2]: > "Both the trend analysis and DID analysis show that the protected bike lane on Second Avenue corridor positively impacted employment, especially in the retail sector, when compared to the Fourth Avenue control corridor"

> "In conclusion, the protected bike lane on Broadway triggered a significant employment increase in the food services industry after installation, indicating an improvement in business vitality as a result."

The overall study finds that

> - On the Second Avenue corridor, the protected two-way bike lane contributed to higher employment and improved business vitality in the retail sector. - On Broadway Avenue, we find that the protected bike lane triggered a significant positive impact on food services employment after installation, indicating an improvement in business vitality as a result."

and > In terms of retail service sector, we found either mixed results or insignificant results. [...] However, the insignificant results may be significant in this context, indicating that there does not appear to be a negative causal impact of right-of-way or parking lane removal on economic outcomes.

Anecdotally, many people in Seattle seem to use the bike lanes, even to commute to work. I also saw a lot of people using them during the world cup.

My own research. I'll compile and publish it.

And yes, I'm _very_ aware of these papers. I used the same methodology as they did :) Note the timestamp on them, they are from the time when Seattle was booming.

And I even specifically looked at the Fourth Avenue that they used as a control because it also got a protected bike lane.

I have _not_ yet checked this hypothesis thoroughly, but from a cursory look at the data, the increase in business can be explained by highly-paid professionals moving into dense housing nearby (we can see that by looking at real estate prices and historical apartment rent data) and by tourists from cruise ships. It's further corroborated by the fact that the percentage of bike commutes did not increase significantly enough.
