Mabuhay @sotm! If you’re in Manila for #sotm #sotm2025, come find @mxn for some troublemaker’s stickers!

The South Bay is looking a little busier in #openhistoricalmap. @impiaaa imported comprehensive historical coverage of #trafficlights from #sanjose #dot. Now you can tell when major streets were built based on when the traffic lights came on […]

[Original post on sfba.social]

In 1960, there were only a handful of traffic lights downtown. The city limits were starting to expand to the east. A railway line still ran north and south along the east side.

Today, series of traffic lights indicate where major arterial streets run, such as Story and King roads. The Guadalupe and Sinclair freeways cut across the city, and a large interchange with the Bayshore Freeway dominates the right side of this map.

Whether you go big or go small, you can’t map it all. But you can lay a foundation to grow and guide a new historical mapping community. @mxn mixes as many metaphors as possible to show us how:
