(built 1889, rebuilt 1954), the Burrard Street Bridge (built 1932), and the Cambie Street Bridge (built 1912, rebuilt 1984). Auto traffic to North Vancouver was facilitated with the construction of the first Second Narrows Bridge in 1925 and by the completion of the Lion's Gate Bridge, in 1938, across the First Narrows. In 1923 Warren Harding became the first US President to set foot in Canada. He met with the Premier of BC and the Mayor of Vancouver and spoke to a crowd of 50,000 in Stanley Park. A monument to Harding designed by Charles Marega was unveiled in Stanley Park in 1925. Labour disputes Although the provincial resource-based economy allowed Vancouver to flourish, it was nonetheless not immune to the vagaries of organized labour. Two general strikes were launched by labour groups during the years following the First World War, including Canada's first general strike following the death of a trade unionist, Ginger Goodwin. Major recessions and depressions hit the city hard in the late 1890s, 1919, 1923, and 1929. Great Depression BC was perhaps the hardest Canadian province hit by the depression. Although Vancouver managed to stave off bankruptcy, other cities in the Lower Mainland were not so lucky, such as North Vancouver and Burnaby. Vancouver also happened to be the target destination for thousands of transients – unemployed young men – who travelled across Canada looking for work, often by hopping on boxcars. This was the end of the line and had for years been a "Mecca of the Unemployed" because, as some cynically joked, it was the only city in Canada where you could starve to death before freezing to death. "Hobo jungles" sprouted up in the earliest days of the depression, where men built makeshift shanty towns out of whatever they could find (or steal). The largest of these was shut down allegedly for being unsanitary. Vancouver was also the launching pad for the Communist-led unemployed protests that frequented the city throughout the decade, culminating in the relief camp strike and the On-to-Ottawa Trek in 1935. Communist agitators and their supporters also led strikes in other industries, most notably the 1935 waterfront strike, and organized a large proportion of the Mackenzie-Papineau Battalion from Vancouver to fight fascism in the Spanish Civil War as Canada's (unofficial) contribution to the International Brigades. Asian immigrants Economic hard times fuelled social tensions. In particular, members of the new and
