The transcontinental railroad had to cross the Sierra Nevada mountain range in California. This challenging terrain posed significant engineering difficulties, leading to the construction of tunnels and bridges. The most notable tunnel is the Summit Tunnel, which was one of the longest tunnels of its time. The railroad's completion in 1869 significantly improved transportation and commerce across the United States.
