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 noise and air pollution while enhancing community identity. This approach aims to improve traffic flow, connect the community, and add economic value in a more cost effective and environmentally friendly manner.
