Cable service began on Maand ended October 21, 1906. tunnel in exchange for payment, moving a bridge, rehabilitating, and maintaining the tunnel. Cable service Īn 1886 ordinance allowed the North Chicago Street Railroad to use the LaSalle St. A third tunnel next to Van Buren St., also connecting the West Side, was built later. connected the North Side and one under Washington St. But the city had previously built two horse and pedestrian tunnels under the river, both were in poor condition and neither was being used. Heavy river traffic and flat terrain required movable bridges, causing long traffic delays, and which could not have cables on them. The Chicago River was the city's port, and shipping had priority over land transport. To enter downtown cable cars would have to cross the river. But the Chicago River, with its two branches, separated the North and West Sides from the downtown and South Side. Used as the backbone of a system of local horse and electric lines, the cable lines were immediately successful and greatly improved public transit in the South Side. In 1882 the Chicago City Railway opened the first of two cable car lines south from the downtown business district. These tunnels should not be confused with a network of small freight tunnels under the downtown area.
In 2010 all approaches had been covered but two tunnels still existed.
One ended regular service in 1924, one was closed in 1939, and one remained in regular service until 1952. All would reopen for streetcar service, but with the change to electricity streetcars could cross bridges and the tunnels were less important. In 1906 all Chicago cable lines were converted to electricity and the tunnels were closed. Two existing public tunnels were converted for cable use, and a third was built as a private venture. Heavy shipping traffic required movable bridges, which cable lines couldn't cross. After cable service ended they would be used by electric streetcars.īy 1900 Chicago had a cable-based transit system that carried 80 million passengers a year, but all cable routes leaving downtown to the North or West had to cross the navigable Chicago River. Two were built for pedestrian and horse traffic and later converted, the third was built specially for cable-cars. The proposed diversion system will divert stormwater in excess of 24 inches (61 centimetres) from the NBCR to the NSC in order to help mitigate the City of Chicago’s chronic flooding problems in the Albany Park area during extreme rainfall events.Between 18 Chicago had three cable car tunnels under the Chicago River. The result? We developed the detailed design of a 5,807-foot (1,770-metre) stormwater diversion tunnel that would connect the north branch of the Chicago River (NBCR) to the North Shore Channel (NSC). We also completed studies of the existing storage and drainage conveyance systems. Other key elements of the project included participation in meetings with the local stakeholders, permitting, data collection and management, visits to the project site, and review, modification, and application of existing detailed GIS-based H&H models. Our design services included tunnel and shaft design, GBR development, and preparation of contract documents. The City's department of transportation selected us to provide design, project management, sub-consultant management, and construction cost estimates. This meant extensive property damage to areas in and around Albany Park. The City of Chicago was experiencing overbank flooding during periods of high water flow.
