^ Agreed, however at least 70 mph is better than 65 mph.
Perhaps it will be increased to 75 mph in the next couple of years - remember 70 mph is the default limit that applies once a new facility is constructed.
My hopes for any increase is basically gone...
The last segment of SH-99 to still retain a 75 mph speed limit, the newer portion between I-45 and I-69, has been lowered to 70 mph, according to December 2022 Street View, just like the portion to the west was lowered in phases over the last few years down to 65 mph. It was still posted for 75 mph this past summer.
What is the reason for these decreases? I drove the road between I-10 west (Katy) and I-69 north this past summer, and the road can easily handle 75 - 80 mph travel throughout. Even on the 65 mph portions that used to be 70 mph or 75 mph, traffic was still moving at 80+ mph. The decreases have done nothing except create an artificial limit that is not obeyed, on a roadway that was designed for faster travel.
I'm expecting the entire northern loop of SH-99 to eventually be lowered to 65 mph, along with the newest 2-lane toll road portion down to I-10 east.
I'll add this: I find it ironic a lot of the northern part of the loop was opened at 65 mph or 70 mph, increased to 75 mph, then decreased back down within just a couple of years.
