The study is needed to make it safer and less stressful for people walking and biking, identify pedestrian and bicycle improvements for the corridor, improve mobility and connectivity for all modes of transportation and identify the vision for the corridor.
Study process
The study will:
- Review existing and future conditions along the SR 99 corridor.
