to the North or West had to cross the navigable Chicago River. Heavy shipping traffic required movable bridges, which cable lines couldn't cross. Two existing public tunnels were converted for cable use, and a third was built as a private venture. In 1906, all Chicago cable lines were converted to electricity and the tunnels were closed. All would reopen for streetcar service, but with the change to electricity streetcars could cross bridges and the tunnels were less important. One ended regular service in 1924, one was closed in 1939, and one remained in regular service until 1952. In 2010 all approaches had been covered but two tunnels still existed. These tunnels should not be confused with a network of small freight tunnels under the downtown area.

History

Background

In 1882, the Chicago City Railway opened the first of two cable car lines south from the downtown business district. 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. But the Chicago River, with its two branches, separated the North and

Sides from the downtown and South Side. To enter downtown cable cars would have to cross the river. The Chicago River was the city's port, and shipping had priority over land transport. Heavy river traffic and flat terrain required movable bridges, causing long traffic delays, and which could not have cables on them. But the city had previously built two horse and pedestrian tunnels under the river, both were in poor condition and neither was being used. One under LaSalle St. connected the North Side and one under Washington St. the West Side. A third tunnel next to Van Buren St., also connecting the West Side, was built later.

Cable service

An 1886 ordinance allowed the North Chicago Street Railroad to use the LaSalle St. tunnel in exchange for payment, moving a bridge, rehabilitating, and maintaining the tunnel. Cable service began on March 26, 1888 and ended October 21, 1906. In 1888, The West Chicago Street Railway (WCSRy) made a similar arrangement with the city over the Washington St. tunnel. Cable service began August 12, 1890 and ended August 19, 1906. The last tunnel was built privately by the WCSRy next to Van Buren St. Construction began in 1890 but went slow and the tunnel didn't enter service until July 27, 1893. It was closed for cable July 22, 1906. When built all three tunnels were 18 feet under the riverbed, but in 1900 the direction of the Chicago River was reversed by deepening it. The lower bottom level exposed all three tunnels and ships ran aground on the Washington St. tunnel. In 1904, the Federal government declared that all three tunnels were hazards to navigation and had to be removed. In 1906 all cables, which had become obsolete, were replaced by electric service that could cross the bridges and all three tunnels were closed.

After cable service ended

After the end of cable service all three tunnels were lowered, converted to electricity, and reopened. The LaSalle and Washington St. tunnels were owned by the city, but the privately owned Van Buren St. tunnel would have to be lowered or removed at the owner's cost. The WCSR filed a suit that went to the US Supreme Court, but they lost and had to pay for lowering the tunnel. The Van Buren St. tunnel was reopened in 1910, the Washington in 1911, and the LaSalle in 1912. The Van Buren St. tunnel was closed again in 1915-1916 during construction of the new

. With the change to electricity cars could cross bridges and the tunnels were less important. The Van Buren St. tunnel ended regular service on September 14, 1924, after that it was sometimes used as a bypass when bridges were open. The LaSalle St. tunnel was closed in 1939 for construction of the State St. subway. The Washington St. remained in regular service until 1952.

Construction

Washington St.

Originally built for pedestrians and horse-drawn traffic, this was the first tunnel under the river. Construction began in 1867 and it opened January 1, 1869, but it wasn't successful. The approach grades were steep for horses, it leaked, and it was dark and uncomfortable for pedestrians, by 1884 it had been closed as unsafe. In 1888 the West Chicago Street Railroad Co. began to rehabilitate it. On August 12, 1890, cable car service began and continued until August 19, 1906. The east approach began in the middle of the street just west of Franklin St. The track descended and was covered. Under the river the tunnel had two horse and one pedestrian lanes. West of the river the approach climbed and the track came to street level just east of Clinton. The tunnel, including the approaches, was long. After closing in 1906, a wider and deeper replacement was built under the original and the approaches were deepened to the new lower level. The grades were aligned for the cars to enter a shallow subway just below street level but the subway was never built, concrete ramps raised the tracks up to street grade. It opened to electric streetcar service on January 29, 1911. The tunnel was in regular use until 1953. By 2013 the tunnel was closed and both approaches had been covered.

LaSalle St.

Originally built for pedestrians and horse-drawn traffic construction started right after the Washington St. tunnel was finished, but was built to a different design. Like the Washington St. tunnel, approach grades were steep for horses, it leaked, and it was dark and uncomfortable for pedestrians. In 1888 the North Chicago Street Railroad leased the tunnel and began to rehabilitate it. On March 23, 1888 cable service began and continued until October 21, 1906, when it was closed for lowering. The north approach began in the middle of the street just north of Hubbard St. (Michigan St. in 1871). The track descended and the approach was covered. Under the river the tunnel had two horse and one pedestrian masonry arch lanes. South of the river the approach climbed and the track came to street level just north of Randolph St. The tunnel, including the approaches, was long. A replacement tunnel was built in a

on Goose Island from steel plate. When the tunnel closed the replacement was lowered into a trench in the riverbed and the approaches were deepened to a new lower level. Like the Washington St. tunnel the grades were aligned for the cars to enter a shallow subway just below street level. The subway was never built, concrete ramps raised the tracks up to street grade. The deepened tunnel was opened to electric streetcar service on July 21, 1912. It was in regular service until November 27, 1939, when it was closed during the construction of the Milwaukee-Lake-Dearborn-Congress subway, the Lake & LaSalle (now Clark & Lake) station of which intersected the tunnel's south ramp under Lake Street. As of 1954, the north tunnel portal was still extant, but both approaches are now filled in, although the tunnel itself still exists under the river. A ramp in the middle of LaSalle St. south of Kinzie St., an access down to Carroll Ave., is sometimes mistaken for the north portal, which was a block north and aligned below the current ramp.

Van Buren St.

The Van Buren St. tunnel was the last of the three built, and the only one built privately specifically for cable cars. Construction began in 1890 but progress was slow. Cable service started on March 24, 1894 and ended on July 22, 1906. The east approach began at Franklin St. Unlike the city-owned tunnels, it didn't go under the street itself, but 150 feet north of and parallel to it. This meant the cars had to slow down, turn north on Franklin, then immediately turn west into a driveway to the approach. It was a stone walled wide ramp which descended at 12% for before being covered under an alley. As the shortest tunnel it had the steepest grade. Under the river the tunnel had a single two-lane arched roof. West of the river the approach climbed to Clinton St. where the line had to turn south. Because of the entrances and steep approaches the tunnel always had operating problems. The tunnel, including the approaches, was long as built. A deeper replacement was built thru the original tunnel and opened to electric streetcar service in 1910. Closed again in 1915 to construct the approaches to the new Union Station, it was reopened in 1916. Closed to regular service in 1924, the tunnel was sometimes used until 1952, when all service ended.

The plan was cancelled in April 1962, although the design and placement of the Peoria Street station house went unchanged.
