This book is based on an institutional evolutionary theoretical view to the G ta kanal. Canals were the major transport infrastructure system besides roads and maritime transport until railroads were introduced. The canal studied is the Swedish G ta kanal project during the preparation and construction phase from 1800-1832. Thus, the G ta kanal, and the canal-era, is seen from a technological, an economic and a political perspective. Comparisons are made with two contemporary major canal-projects; the Erie Canal in the USA (1817-1825) and the Caledonian Canal in Britain (1804-1822). It is argued that the G ta kanal project, as Sweden's Mega Project of its time, represented an important development step in Sweden as regards learning and innovation and became a starting point for Swedish transport infrastructure projects in the time to come, primarily the railways.
