|LaSalle Street Tunnel (colorized)|
This tunnel, along with the Washington Tunnel, were valuable escape routes during the fire of 1871, which quickly consumed the wooden bridges over the Chicago river.
When the tunnel closed to cable cars in 1906 the replacement was lowered into a trench in the riverbed. It opened to electric streetcar service in July 21, 1912.
