I decided to make this a modular asset, so that I can build multiple viaducts of varying lengths. Making the model itself in Maya was not that difficult but I made the mistake of UV mapping the most complex part of the arch first, which involved a lot of restructuring the UV for the on/off ramp sections (that have no arches). So, the drive to avoid brainwork ended up in a different kind of brainwork.
Still, it was a good way to get back into modelling and UV mapping - better to get accustomed to it now than much later on when i'm pressed for time and probably panicking!
