The new transportation system is considered a megaproject due to its enormous budget and scale.
Megaproject is formed from "mega-" (from Greek "megas", meaning large or great) and "project" (from Latin "proicere", meaning to throw forth or put forth). The term refers to a large-scale project that is significant in size, cost, or complexity.
Think of 'mega' meaning large or great, and 'project' meaning to put forth. This helps you remember that a megaproject is a large-scale endeavor.
