Engineering Directives

From time to time MassDOT issues formal Engineering Directives to introduce new design standards or engineering procedures, or to supplement, clarify, or amend existing design standards or engineering procedures. These Directives should be used by designers, contractors, MassDOT employees and other parties in conjunction with other MassDOT design and construction publications, such as the Project Development and Design Guide and the Standard Specifications for Highways and Bridges.

All Engineering Directives issued by MassDOT (formerly MassHighway) since 1992 are available to download from our Engineering Directives Table.

MassDOT also issues Policy Directives for various reasons. All Policy Directives issued by MassDOT (formerly MassHighway) related to design or construction procedures are also available to download from our Policy Directives Table.
