Where did the First Transcontinental Railroad's famous “Last Spike” ceremony take place in 1869?

The First Transcontinental Railroad's famous “Last Spike” ceremony took place at Promontory Summit in Utah Territory.

On May 10, 1869, the Union Pacific and Central Pacific railroads met at Promontory Summit. Central Pacific president Leland Stanford ceremonially drove a golden spike with a silver hammer, marking the joining of the rail lines. The event is also called the “Wedding of the Rails.”

The railroad connected the existing eastern rail network near Omaha and Council Bluffs with Sacramento and, through later extensions, the Pacific coast. Its completion made travel and freight movement across the United States much faster, safer, and less expensive than earlier routes.

A frequent oversimplification is to say the 1869 ceremony created an uninterrupted rail line from the Atlantic Ocean to San Francisco. The original route still involved transfers and later improvements; the ceremony specifically joined the Union Pacific and Central Pacific lines at Promontory Summit.
