The First Transcontinental Railroad was built crossing the western half of America and it was pieced together between 1863 and 1869. It was 1,776 miles long and served for the Atlantic and Pacific coasts of the United States to be connected by rail for the first time in history.
The Impact of the Transcontinental Railroad. On May 10, 1869, as the last spike was driven in the Utah desert, the blows were heard across the country. Telegraph wires wrapped around spike and sledgehammer transmitted the impact instantaneously east and west.
The impact of the trans continental railroad can not be underestimated or understated. it is what effectively made our nation what it is today by spreading goods and trading routes.
