At that time he made a feasibility study of a Bering Strait bridge and estimated the cost to be $1 billion for the 80 km (50 mi) span. [12] In 1994 he updated the cost to more than $4 billion. Like Gilpin, Lin envisioned the project as a symbol of international cooperation and unity, and dubbed the project the Intercontinental Peace Bridge. [13]
Chacao Channel bridge map. It's a construction project for a bridge that will cross the Chacao Channel. It is intended to unite the Isla Grande de Chiloé with the Chilean continental territory, in the Los Lagos Region. The opening of the bridge is planned for 2025. [97] [98] [99] It will be the longest suspension bridge in Latin America. [100]
When Lin received the National Medal of Science from President Ronald Reagan in 1986, he handed over a 16-page plan for a 50-mile (80-kilometre) bridge linking Alaska and Siberia across the Bering Strait, a project he dubbed the Intercontinental Peace Bridge.

Peace Bridge from Fort Erie, with new lighting retrofit. The building of the Peace Bridge was approved by the International Joint Commission on August 6, 1925. Edward Lupfer served as chief engineer. [2] A major obstacle to building the bridge was the swift river current, which averages 7.5 to 12 miles per hour (12.1 to 19.3 km/h).
This is a list of bridges and crossings over the Niagara River in order from Lake Erie downstream (generally northward) to Lake Ontario.Bridges and crossings marked * cross branches of the river within the United States, while those marked † cross within Canada.
Part of an illustration from Gilpin's treatise. The Cosmopolitan Railway was a proposed global railroad network advocated by William Gilpin, formerly the first territorial governor of Colorado (1861–62), in his 1890 treatise Cosmopolitan Railway: Compacting and Fusing Together All the World's Continents.
Several engineers have designed bridges on various alignments and with differing structural configurations. A proposal by Professor T.Y. Lin for a crossing between Point Oliveros and Point Cires featured deep piers, a length of 14 kilometres (9 miles), 910-metre-tall (3,000 ft) towers, and a 5,000-metre (16,000-foot) span, more than twice the length of the current longest bridge span.
