Smallest radius Loop in Texas?

Is it the one in Crockett? Is there another one I'm missing?

I can't remember if it's a spur or loop but 157 in Teneha is pretty tiny

national highway 1

Wow, Loop 157 is only 1.4 mi long, it could be BUS US 96.

Are you still talking about why 157 in Teneha bc it would be BUS 59 or 84. 96 only begins southeast of Teneha proper

How would you define the radius of that one?

FWIW, it's signed as a Loop. I'm sure there is a way to define its radius given the proper math skills.

You would need to define an arc segment equation (x^2+y^2=C) that represents the least squares fit to the actual loop route. Assuming you can get the centerline defined in GIS or from record plans, it becomes a set of equations mixing algebra, trig, and calculus. Doable, but not something I'd want to dive into.

I don't think all state Loops in Texas are in fact closed loops.  It is still possible to define radius mathematically for open loops, but the exercise loses some of its point.

I was referring to open loops. Closed loops are much easier to define - get the area inside, divide by pi and take the square root.

It doesnt go all the way around, but the one in Gladewater is less than a mile from their downtown.
