Yakima Ave.-Center Street tunnel - Union Pacific Railroad (from copy negative). The first Holy Rosary Church, a wooden structure, is in the background. This is the site of the planned Union Pacific Railroad 8,600-foot tunnel circa 1908. Construction began about 1909 but abruptly halted the following year and was not resumed. It was thought that water conditions may have caused the stoppage. The abandoned tunnel was discovered in 1959 when drilling equipment involved in the construction of the Yakima Street Bridge broke into the tunnel.
