DDOT recently obligated money to hire a contractor to work on the formal design of the rehabilitated Rock Creek Park Trail and is working on selecting a contractor for that.
Meanwhile, DDOT is also planning to do a full reconstruction of Beach Drive from Connecticut Avenue all the way to the Maryland boundary in the near future. This will involve rolling closures of Beach Drive (Gotcardammerung!) and a full rebuild of the road from the bottom up. The road won't be widened, but DDOT is hoping to do some spot work on the trail in conjunction with the road work.
