Constructed in 1869-71, the 2,000-foot (610 m) long tunnel alleviated interruptions from bridge openings due to heavy river traffic and served as an escape route during the Great Chicago Fire of 1871.[2] In 2023, the City of Chicago approved a series of plans to convert buildings on LaSalle Street from office space to residential.In total, plans have been approved to convert five office buildings into residential spaces with 1,600 apartments, 600 of which will be affordable housing.CTA bus route 156 runs through nearly the whole arterial section (from Jackson Boulevard or Adams Street to Stockton Drive).[7] The view facing south down the canyon has been used in the movies The Untouchables, Public Enemies, Transformers 3: Dark of the Moon and Road to Perdition.
