I recently made a thread about what Ireland would be like it we never left the UK or at the very least stayed in it for several more decades. One subject matter that people often being up in this alternate history scenario is how our infrastructure would have developed differently if we stayed in the Union.
Would Dublin have an underground metro system? IIRC this was proposed before independence in the Abercrombie plan with a tunnel from Harcourt St to Broadstone being one element. Retention of the DUTC trams is also a possibility although many such systems in GB cities were removed anyway.
I imagine that some of our railway lines would still be closed but as a result of Beeching's Axe rather than Todd Andrews. However, some lines would surely still be open, the Navan one being quite likely IMO. Perhaps some link to the northwest would remain with no partition. What other lines would likely have remained open?
How would Irish road infrastructure luck under the UK? Would the UK have chosen better routes, for example the M7 to Cork etc? I imagine some roads like the M3 or M9 would not be built in this scenario as the traffic levels did not justify them in our reality and they were really just the product of boomtime confidence.
As for rural electrification, would this still have been rolled out in the same way and on roughly the same timeline? I imagine Ardnacrusha would not be built, this was the jewel in the crown of Free State infrastructure, would there be a similar scheme elsewhere?
I'm not suggesting that we should have stayed in the UK for the benefit of better infrastructure just how it would look like if we had remained, aside from politics.
What are your ideas of how our infrastructure would have developed under Britain?
