Home MenuDesign Guidelines
The Project Design Guidelines are a subsection of the ACHD Policy Manual that developers and builders should follow when building developments that impact the right of way. The design section aligns with District-wide planning and design activities and ensures ACHD, local, state, and AASHTO standards are met.
These standards and guidelines are here to help with the planning of projects and are not a substitute for engineering knowledge, experience, or judgment. Final designs should be of the highest quality possible, consistent with existing conditions.
