What is wrong with this story on a crash?

Hey that's one thing you can't blame the reporter for!
The street naming system is historic in Utah. And while it's confusing at first, when you stop and think about it, it does make finding a particular address very easy. It's based on a grid system. The starting point for the streets, is usually at what was historically the "center" of town.
So for St. George, the starting point is the intersection of Tabernacle St. and Main St. So the first Street West of that intersection, is 100 West St, the first street south of that intersection is 100 South St. Same is true for streets east and north.
This is great for streets running in a more or less straight line.
120 E. is going to be between 1 and 2 blocks east of the prolongation of Main St., and 2680 S. is going to be between 26 and 27 blocks south of Tabernacle St.
Of course in "modern times," they are adding names to the streets. Example, 100 N. is St. George Blvd. Another example 700 E. is also called University.
And then you have all the newer subdivisions that the developers have streets making serious curves and sometimes circles, to cut lot sizes into irregular shapes. Done to let the subdivisions follow the natural geography of the land, and get more lots to sell.
Most of these have street names, rather than just numbers.
But the grid system is a very handy, easy to use system. Almost every town and city in Utah, and a lot of cities and towns across the country use it.
And that is likely much more than you ever wanted to know about street designations.

 

AMEN!
Great Caesar's Ghost! Cotton hits it right on the head again!
