Why does the speed limit drop to 55 once south of 9000 S? It can't be due to asphalt as many highways are 65mph with asphalt.

Mountain View Corridor is a large project that is designed in sections. The section that drops to 55 mph is designed similar to a frontage road whereas the sections that are set to 65 mph are designed as highways. As development continues near Mountain View c and there are larger traffic volumes, we can then look at redesigning other sections of Mountain View to be a highway.
Thank you for your question.

Dimes,
Thank you for your comment. You are correct with the similarities you pointed out between the 55 MPH and the 65 MPH section. There a few things that are different about designing a 55 MPH road vs a 65 MPH that make a big difference. Some of the differences would be the lengths of the acceleration and deceleration lanes, the stopping sight distances, the design of the horizontal and vertical curves, the clear zone be different, the type of barriers, the length of need of barriers, curb and gutter, sign size and other items.
I hope this helps.
