Hi dknelson, you seem to be more knowledgeable about the area (and more experienced than me) so feel free to revert if you deem that the most accurate. 

The reason I made these changes it because SR 73 is still signed for these roads in street level photos on google maps. These are recent as of 2025/2023

Here is exit 279 https://tinyurl.com/yybrdmz3 marked as SR 73

Here is a road sign on the exit ramp
