The new May 2017 schematics have been added to the project website. Someone with a more careful eye than me (MaxConcrete?) may want to take a look at the revisions listed here.

The changes in the new schematics versus the May 2016 schematics are mostly minor. I'm hoping to be able to post a full analysis on HoustonFreeways.com this weekend.

In short

Mid and south side of downtown: minimal changes

North side of downtown
Some beneficial tweaks at the IH 69/IH 10 interchange
The IH 10/IH 45 interchange complex received the most changes, including shifting the IH 10 eastbound main lanes to the west side of the multiplex. There are numerous tweaks, mostly adding lanes to certain ramps, for example the downtown spur connector. All changes are beneficial.

IH 45 between IH 10 and IH 610, including the 45/610 interchange is basically the same.

IH 45 from IH 610 to BW 8 has minimal changes, mostly some ramp repositioning.

Thanks for the tip about the new schematics

After a side-by-side comparison to the May 2017 schematics, there are only two non-negligible changes.
1. The SH 288 toll lanes previously ended/started with a connection ramp into Chenevert street. The residents in that area were complaining about it last year. The ramp into Chenevert is now eliminated. There is now a ramp from the southbound SH 288 frontage road into the southbound toll lane, and the northbound toll lane terminates into the ramp which connects into IH 45 (both northbound and southbound)
2. Changes on the south end of the downtown connector. Last year's design went over West Dallas Street, but the new design goes under Dallas Street and a new overpass over the connector is added at Andrews Street. The northbound frontage road smooth transition into Houston street is eliminated, and it now requires crossing the Dallas bridge with a left turn and right turn. The new drawing also suggests that the Sabine Street bridge over Buffalo Bayou will be replaced.

Item 1 is probably a plus from the mobility perspective. Item 2 has a minimal effect, but probably slightly negative due to the loss of the smooth transition to Houston Street.

Of course I'm disappointed that there are no changes which address any of my items of concern which I posted last year, so I think I can safely conclude that there will be no changes relating to my items of concern

On a more positive note, TxDOT representatives stated in a recently posted video (long video) that the Interstate 10 Express lanes will not be tolled and appear to be restriction-free, and the IH 45 MaX lanes will not be tolled, but will be restricted to HOV vehicles at peak periods.
