Mission
As DDOT owns all right-of-way and infrastructure associated with the interstate, freeway, and local roadway system within the District of Columbia (except roadways maintained by the National Park Service and the Architect of the Capitol). DDOT shall review and approve requests for new or modified access to the District's Interstate and Freeway system based on the following key areas:
Access and Geometric Review
Ensure that the proposed change in access is acceptable in the context of the existing interstate/freeway system, and that the geometric configuration of the proposed plan is acceptable in terms of satisfying the requirements of applicable design standards and sound engineering.
Operation and Safety Review
Ensure that the proposed change in access operates acceptably and does not degrade the operational performance or the safety of the freeway local street network.
Policy and Planning Review
Ensure that the proposed change in access is in compliance with local and Federal policies and is consistent with approved transportation plans.
Noise Policies
In regards to all federal highway projects in the District of Columbia, DDOT should consider noise mitigation whenever a project-related highway traffic noise impact is expected to occur. A highway traffic noise impact is deemed to occur when predicted (design-year) noise levels either approach or exceed the applicable noise abatement criteria (NAC) or substantially increase the existing noise levels.
