This is a list of construction projects in the District of Columbia that are major enough to require changes to the map. The goal of this thread is to coordinate our edits in response to the changing road conditions on the ground especially since satellite imagery and GPS points may not reflect current conditions.

Due to the delay before edits to go live, projects and closures expected to last less than two weeks should be discussed here before editing the map.

Post here to report a construction project - I will add it to the list in order of completion date and acknowledge your post by marking it with "thanks". Also, please notify me of any incorrect or missing information, or upon the completion of a project.

The DDOT Project Dashboard is located here.

The list of active DC Water projects is located here with press releases located here.

Please be aware that a discussion is occurring in this thread in the Wiki Updates and Discussion Forum regarding how to label roads that are closed or under construction.
