The schematics include a sidewalk and bike lanes, though the shoulders/lanes are only 5 ft wide (maybe 6 with the gutter).

The lanes appear to extend to intersections, swapping places with the turn lane (like what was done on Parmer or 290 west of Oak Hill).  Some of these narrow shoulders seem pretty dangerous to me but I guess it's nice TxDOT is at least thinking about bikes and peds for new projects, and leaving asphalt space for all road users.

One downside is parts of 620/2222 near the bypass will see their shoulders will shrink from 12' to 5-6'.
