Bridges and tunnels were crucial for railroads as they enabled trains to traverse challenging terrains, such as rivers, valleys, and mountains, ensuring a more direct and efficient route. They facilitated the expansion of rail networks by connecting previously inaccessible areas, thus enhancing commerce and transportation.
