Encinitas Bike Maps

▶ Live maps: machinesandhumans.github.io/encinitas-bike-maps · Cardiff cycle track

Interactive, spatially accurate maps of four Encinitas road projects, showing where each layout narrows riders' options and where official crashes happened before and after the change.

Start with PROJECT_BRIEF.md for status, data sources, decisions and open items.
