Actually, there are many sections of both the I-5, I-15 and the 163 that are down to various level 2 and 3’s. With some scattered sections of 5. I’m not sure if this is for a reason, but it has been several different editors that have unlocked them. Seems to me that a major highway in SD should all be locked at 5. If I am mistaken please let me know.
I know it’s broad, but all of the freeways in that area have various sections down. I went and tried to get everything at least to 3. But could have missed some. A lot of the ramps are down as well. Gonna be a pain to clean up.
