Knox Street is about to undergo some serious change for the better. Sometime later this year or beginning of next year (2017), the road will be reduced to one lane each direction and a turning lane. This initiative (Dallas Complete Streets) was started several years ago with city bond funds and may be supplemented with PID funds. The link is below if you want to delve in to the detailed renderings and options, but the jist is that the lanes are being reduced, the crosswalks are being improved, the sidewalks are being widened, and parking along Knox is going to be angled to make it easier to get in and out of the spots.
Last week a survey crew was out on Knox which I believe was in relation to this project. Last I heard, this project is at the bidding stage. More information at: https://dallascompletestreets.wordpress.com/category/knox-street-complete-streets-project/
