2) Panama Canal
3) Suez Canal
4) Erie Canal

Answer 1

The First Transcontinental Railroad was constructed across the U.S. during the 1860s, connecting the east to the west coast, and the correct answer is 1) Transcontinental Railroad.

Step-by-step explanation:

During the 1860s, the First Transcontinental Railroad was constructed across the entire United States, connecting the east coast to the west coast. This monumental engineering feat, which was the first of its kind in the world, linked Omaha, Nebraska, with Sacramento, California, and was largely financed by an 1864 grant of federal lands to the Union Pacific and Central Pacific railroads. Thousands of workers, including Chinese for the Union Pacific and Irish immigrants as well as Civil War veterans, labored under daunting conditions to complete the railroad. The railroad was completed when the westbound Union Pacific crews met with the eastbound Central Pacific on May 10, 1869, at Promontory Point, Utah, thus marking a pivotal moment in American history and significantly bolstering westward expansion and commerce.
