Does a town upgrade to 24 or higher still increase the number for the first path-improvement

Hello

As I upgraded my capital town to level 11, I unlocked the first path-improvement (reinforced with small grey rocks instead of just brown dirt and wooden bridges instead of just stepping-stones in the rivers, generates 5 coins / 10s /tile).

But the number of tiles for this type of paths is limited by number and levels of owned towns:

A certain number of tiles, that i don't know is added by upgrading a town to level 11 and one tile for each following level.

As I recently upgraded my capital to level 24, I unlocked another path-improvement:

These paths are reinforced with larger grey stone-plates, the bridges are stone-bridges and this type generates 15 coins / 10s / tile.

Do towns of level 24 and higher only add to the second path-improvement, when leveled up further, or also still to the first path-improvement?
