when was the big walker mountain tunnel built
Big Walker Mountain Tunnel The 4,229-foot (1,288Â m) tunnel was first opened in 1972 after five years of construction labor. It carried a price tag of $50 million, which at the time was the most expensive single project undertaken on Virginia's interstate system.[1] The opening of the tunnel reduced the travel time from Wytheville to Bland County by 30 minutes.[2]
History of Minnesota After the Civil War, Minnesota became an attractive region for European immigration and settlement as farmland. Minnesota's population in 1870 was 439,000; this number tripled during the two subsequent decades.[69] The Homestead Act in 1862 facilitated land claims by settlers, who regarded the land as being cheap and fertile. The railroad industry, led by the Northern Pacific Railway and Saint Paul and Pacific Railroad, advertised the many opportunities in the state and worked to get immigrants to settle in Minnesota.[70] James J. Hill, in particular, was instrumental in reorganizing the Saint Paul and Pacific Railroad and extending lines from the Minneapolis-Saint Paul area into the Red River Valley and to Winnipeg. Hill was also responsible for building a new passenger depot in Minneapolis, served by the landmark Stone Arch Bridge which was completed in 1883.[71] During the 1880s, Hill continued building tracks through North Dakota and Montana. In 1890, the railroad, now known as the Great Northern Railway, started building tracks through the mountains west to Seattle.[72] Other railroads, such as the Lake Superior and Mississippi Railroad and the Milwaukee Road, also played an important role in the early days of Minnesota's statehood. Later railways, such as the Soo Line and Minneapolis and St. Louis Railway facilitated the sale of Minneapolis flour and other products, although they were not as involved in attracting settlers.[71]
