Just a nitpick: there actually are two subway lines in Rome too. They're building the third one and yes, it's incredibly complicated because you can't dig a hole anywhere in Rome without finding something of historical relevance :)
- jahnu 11y agoCould they not just go deep enough to avoid all that?
- danmaz74 11y agoThat's something I often wondered about, but I'm pretty sure there will be some reasons why it's not feasible... I also think that the biggest problems are the stations.
- din-9 11y agoSubway lines need stations, ventilation and often big shafts to build the tunnels from.
- jccooper 11y agoThe lines are deep enough, with tunnelling, to avoid historical layers; mainly it's the stations that end up with archaeology.
