Highway Program
The Highway Program within the Bureau of Project Development of MaineDOT is responsible for design and construction of projects to improve the safety and mobility of Maine’s highways and streets for all users.
This site is divided into three sections containing design and construction policies, practices and procedures, engineering instructions, design guidance and other information relative to the Program’s responsibilities:
- General - This section contains all of the Program’s processes, forms, and general procedures that apply to all highway projects.
- Design - This section contains the Program’s practices and procedures related to the elements of highway design. It also contains related engineering instructions, design guidance and other references. Practices and procedures, engineering instructions and design guidance are based on A Policy on Geometric Design of Highways and Streets by the American Association of State Highway and Transportation Officials (AASHTO) also known as the AASHTO Green Book, or other related documents and publications. For further information, refer to the AASHTO Green Book or the other references provided for each highway design element.
- Construction - This section contains the Program’s references, documentation, forms, policies, and practices and procedures for highway construction.
