Channel Tunnel (1987-1994)
Britain and France built a 50-kilometer rail tunnel under the English Channel, one of the largest private infrastructure projects ever attempted. Political delays, geological surprises, and financing problems pushed it years past schedule and billions over budget.
The tunnel opened in 1994 several years late and nearly bankrupted its operators.
It became a durable cross-border link now carrying high-speed rail and freight, and a standing cautionary tale about mega-project cost control.
SuedLink shares the profile: an oversized, politically contested crossing that took years longer and cost more than planned, yet delivers lasting value once complete.
