The Oak Hill Expressway project proposes a more sustainable and community-focused approach to transportation infrastructure. Key elements include expanding the right of way, relocating the Capital Metro park and ride, and relocating the Old Rock Store to incorporate low impact development techniques like biofilters, permeable pavement, and vegetated swales to treat stormwater. The project also aims to restore Williamson Creek, plant over 1,000 new trees, and incorporate a green wall to reduce pollution and noise impacts. This approach aims to improve mobility while enhancing the environment, connecting the community, and adding long-term value.
