Before (2023) / After (2026) the pedestrianization and greening of a big part of Place Félix Éboué in Paris’s 12th arrondissement. The difference will be even more striking once the trees have leaves ;)

Thank you to everyone who came out for the #AlexPretti memorial ride in Oakland today. It was a huge turnout, even more than shown here at Lake Merritt, as some people peeled off since the start at Rockridge BART. @bikeeastbay.bsky.social @ebbp.bsky.social

As the Co-Chair of the DOTI Advisory Board, I don’t take criticizing the Mayor lightly. But we just hit the highest number ever of people killed in traffic crashes in Denver, and it’s not a priority for Mayor Johnston. Something needed to be said.

What's especially fun about yesterday discovering my shoutout in Life After Cars, is that this evening I'm delivering a talk to @wesmars.bsky.social's class at CU Denver on my exploits in tactical urbanism, for I believe the 7th year in a row.

Colfax BRT is really happening, and I couldn’t be more excited! This is the first canopy structure that I’ve seen, and it feels like they’re making really good progress.
Still wish there was bike infra included as part of the project tho…
