Project Mystery

This channel produces long-form documentary videos exploring large-scale infrastructure, engineering projects, and the systems that shape modern society.

Each video focuses on how complex projects are designed, built, delayed, or reworked — examining the technical, economic, historical, and environmental factors behind them. Topics include transportation networks, water systems, energy infrastructure, and major public works across the United States and around the world.

All documentaries are researched and written with an emphasis on factual accuracy, context, and explanation rather than speculation or sensationalism.

New videos are published several times per week.

Sources are drawn from public records, engineering reports, and historical documentation where available.
