For Once, Some Good Unintended Consequences on Irving
Two things I've noticed over the years along Irving have been the fact that many drivers seem to get confused and think that Irving has two lanes going in each direction, which it does not. This often leads to impatient drivers trying to pass, only to nearly kill people de-boarding the N.
The other has been the total cluelessness many drivers have when it comes to turns in a busy intersection. At 9th and Irving, impatient drivers would often try crashing through the wall of people crossing on the "Walk" sign to turn right onto 9th.
Likewise, it seems that the rules of the road concerning left turns is no longer taught at driver's school - people just turn even if there's a conga line of cars approaching. Now, banning left turns (or all turns) at 9th and Irving wouldn't solve anything - but for now, things have calmed down. Why? Because the road construction has made it nearly impossible for over-stimulated drivers to plow through pedestrians, all to save .001 seconds at the light.
So, never let it be said all unintended consequences are bad. For now it's a lot safer (if a bit stranger) crossing at 9th and Irving than it was before. Let's hope the new improvements help calm things down.
