Izgrađeno je puno podzida, tunela i usjeka, a zbog čestog prelaska s jedne na drugu stranu rijeke i dosta mostova tako da je ta dionica bila puno skuplja nego dionica izgrađena prije.
It was built much of the foundation, tunnels and cuts, due to the frequent switching from one to the other side of the river and a lot of bridges so that the stock was more expensive than a stock built before.
