> And if it's doable in a densely populated country like the Netherlands then it's doable anywhere.
There's three different "doables" at play here:
- technically doable: can you actually convert the level crossing to an underpass or a bridge? For example, it's hard to do an under/overpass when there is a river 10m away, or when everything bar the road/rail and a bit of space is filled with buildings.
- financially doable: is there actually enough budget in the city/responsible authority's coffers?
- politically doable: will the population support the necessary construction works and the limitations that come with it? Like, will there be heavy protests of people that rely on either the rail or the road to get to work and would require massive amounts of time to bypass?
It is rare that there is a combination of all three being true, with the exception of course being tragic disasters with people and especially children dying as such events usually eliminate the political and financial blockers.
