Big fixes may require help from town or city officials, like installing a traffic light or stop sign in a dangerous intersection—in that case, be the squeaky wheel and consult our guide to getting things done.

Make your own bike lane
Transform your corner bus stop or an abandoned phone booth
Create your own signs for bike and pedestrian safety
Trim that tree that's blocking the stop sign on the end of your block
Plant seed bombs or native plants to give life to a dreary landscape
