That's because they don't widen the roads enough. Each added lane adds capacity. I'm talking about local roads, not highways. On highways, people merging on and getting off cause a lot of the congestion. Especially when the off ramps back up because the roads that they are connecting to can't handle the number of vehicles. The problem is exacerbated by the fact that a huge percentage of drivers don't know how to merge smoothly.
Widening local roads can have the same induced demand issue as highways. Widening 192 to 4 lanes each way would probably help for a month or two before people change their travel routes to fill it back to capacity. You could increase Old Lake Wilson to a 4 lane road and the daily backup would likely still reach back to at least the Reunion bridge. It’s not a problem unique to limited access highways. You would have to massively overbuild a road and then see a lot less development than planned for more lanes to be “helpful” (see I-Drive South, aka World Gateway/Xentury City).
