SimCity Classic Cheats

Water cannot normally be bulldozed, except fringes, but it can be turned into land. Smother it with road, forming intersections, and beneath will be considered land. Bulldoze the road and land will appear. Note that for water>land, road has to be on all four sides and above the water. This means at edges of the map, water can't be removed.

It's easiest to add roads in columns/rows, or roads may not connect and you must bulldoze and retry. It is advisable to do this with the game at pause speed, or bridges may form that may become irremovable.
