Grid builders and shoreline roads builder
The grid builders will remove much that exists in their path (so plan ahead before using!) except water and the freebuilt road they build. Also, they build pipe and underground wires. The process will cover uneven terrain, but the road is only built on flat sections.
The shoreline road builder only builds the freebuilt road along the shoreline and nearby islands. You will have to optimize the results.

Also a water road and a water alley that build as a road, but place water instead.

The freebuilt road is slower than the in-game dirt road and uses the same graphics. Thanks Lobby!
