Looks like:

- The current street names look correct based on 2022/2023 dashcam footage.
- This "Old Katy Road"+"Katy Road" intersection may have been redesigned between 2015-2022.

5 months ago, this changeset adjusted some things too:

- https://www.openstreetmap.org/way/423460691/history/3

- - -

Checking the few business websites along this small stretch of road... The:

- South ones have addresses as "Old Katy Road".
- North ones have addresses as "Katy Road".

I'm suspecting they'll still get deliveries, and anything using either Old/No-Old name would be a match.

(Someone more familiar with Texas/Houston/addresses or this county would probably know more details.)
