I think this was a good move for K street because H street connects to Florida Avenue and Benning Road whereas K street is a collector road. Unlike 14th street and 16th street where they are more important in different places(north of U street for 16th/south of U street for 14th) Having K street as secondary is better, knowing after being a US 29 main road, wasn't really significant after Mount Vernon square and was only a collector. This was a right move.
