I don't know if this has been suggested before, but I'd like to see some changes in land transportation.
Roads would no longer be built on each tile to improve trade, but would be built from one city to another. This would make sense graphically and realistically as the current roads in Civ 3 are kinda silly looping and swirling everywhere.
Roads would still give three movement, but the main advantage of roads would be to connect cities to each other and to resource colonies for trade. Once you irrigate or mine terrain, it gives the same movement advantage as having a road built there so there is no need to road each and every square for transportation, but you'd want to plan your roads so as to build only as many as you need.
Bridges would be a learned ability. In the ancient age, you would get small bridges that could be built over small rivers, rivers large enough for ships to sail and canals could not be bridged until later.
Once built any civ may use that road, whether they are your allies or enemies. This makes sense because armies move faster along a road, never mind who built it. Enemies would not get the movement bonus from your irrigation and mines though, and allies would need a ROP to use these. This would discourage the building of roads on every single tile, as an enemy would then have three movement over your entire country rather than just along the roads.
Rails would follow the same design. They may only be built along an existing road and would provide more (but not unlimited) movement to your troops. Rails would also be required to trade certain resources across land. For example if you had a road connection to a city it would have access to horses, iron, saltpeter and coal but you would need a rail connection for oil and uranium. Enemies would not be able to use Rails until they had captured the Cities that those rails connect and allies could use them with a ROP.
Roads and rails can be pillaged (separately), breaking the trade link between cities, so they must be protected. This makes pillaging much more effective as some well timed raids can cut off a city from an opponents trade network.
