Question of the Week: How Can I Encourage City Leaders to Not Widen a Neighborhood Street for Cut-through Traffic?


Every week, we take one of the best questions submitted to the Strong Towns Knowledge Base, and we answer it here. This week’s question: How can I build a coalition of strong citizens in my town?

The Knowledge Base is a crowd-sourced repository of your questions and answers about how to build a strong town. We on the Strong Towns staff chip in when we can, but we can’t get to everything—which is why we encourage all of our members and readers to head on over and add not only questions, but comments with any additional advice, useful links, or wisdom you have to offer!
