Do DC 311 and Twitter. And Facebook. I reported terrible road conditions north of the Lincoln Memorial a few years ago. (There was construction nearby, but the road was still open, so I thought it should still be in a usable condition.) I don’t ride on that street too often so I forgot about my complaint. Then about two or three years later, I received an email update that the issue had been resolved. I barely remembered filing the complaint.
The point? Sometimes DDOT can take a LONG time to take care of a problem.
I’ve also reported other issues that were resolved much quicker than 2 or 3 years. They repaired the crumbling concrete on the 15th Street protected bike lane, next to the Treasury Dept., just a few weeks after I complained about it on DC 311. If you also post on Twitter and Facebook, you might increase the chances of a quicker resolution.
