Allow pak-sets to define a bridge type depending on time to be built during road building phase of world creation.
Pak sets can already specify the standard road type to be used during world creation in simuconf.tab:
# City roads timeline. Format examples:
# city_road[0]=name,1900,1920
# city_road[1]=name2,1921,1950
city_road[0]=city_road,1905,2050
city_road[1]=cobblestone_road,1781,1904
city_road[2]=dirt_road,1700,1780
The choice depends on the start date of the map, types and the time interval they should be used can be given (as seen in the example from pak128.britain above).
It would be desirable to have this functionality also for bridges to avoid both, anachronisms and needlessly reduce put chores on the players who might have to replace a multitude of bridges.
This is a good idea indeed. Adding the ability to do this for roads has already been very useful.
I support this, definitely a configurable that is currently missing.
Definitely support this.
The dates should overlap, I think, since upgrading of roads from one type to another is not instantaneous, even for new projects.
