Regarding the new SPUI for the I-79 Wexford interchange, I mostly endorse it, though I do have some issues, the most prominent of which being the two east-bound turning lanes coming from 1-79 N, which is the whole reason for the redesign. Currently the exit (going northbound) has three lanes: one heading west toward Nicholson, middle lane turning east onto 910 where the driver gets to choose which of the two eastbound lanes to turn into (left lane for Mingo, right lane for 910 E), and the right lane for Brandt School. With the new redesign, drivers going eastbound on 910 and looking to turn onto Brandt will have to share the right lane, as the middle lane is slated for the left lane on 910, which quickly turns into a turning lane for Mingo. My fear is that once this is recognized by drivers, the right lane will be bogged down and cause traffic hiccups, as no one will want to deal with merging from the left turn lane once already on 910 E.
I also have concerns about the decel lane from I-79 N. I think (and have thought this for years, growing up in the North Hills) the fourth lane coming from I-279 needs to be extended through to the Wexford exit. Yes, that'd cause some weaving issues for drivers coming from I-79 rather than 279, but it would eliminate the merging headaches.
