What projects would you advise the iron throne to do like roads or canels? Would it be possible for the westros levels of government?

Canals – a Blackwater-to-Mander canal and a Blue Fork-to-Ironman’s Bay canal would be first priority. After that, probably a White Fork to Torrhen’s Square canal. Canals and/or irrigation linking the Scourge to the Yronwood river would probably also be a good idea. 

Roads – extend the River Road to Maidenpool, build a Gold Road to River Road connection that connects Stony Sept and Riverrun, a White Harbor connection to the Kingsroad, the Westerlands could use a coast road that connects Banefort and Kayce to Lannisport, the Reach could use a ringroad that connects Old Oak, Goldengrove, and Bitterbridge, the Stormlands could use a road that connects Massey’s Hook to the Kingsroad, and an extension of the Kingsroad to the Boneway through the Rainwood connecting Rainy Town.
