Access roads were originally 60mph, before construction, and have since fluctuated between 45mph, 65mph, and now 40mph. As of the time of this writing, there are no visible ‘work zone’ indicators along this stretch, and the road is clearly designed for speeds far exceeding 40mph. There’s usually a cop sitting there just before the on-ramp (where people are expected to accelerate onto the freeway), and cannot be seen until it’s too late.

Note: Based on first hand experience, and continued observations, these cops are NOT there to enforce the speed limit for reasons of public safety. Their turn around times between stops are incredibly short. They’re milking that gold mine for revenue, before TXDOT receives enough complaints and corrects it.
