English: Chambers Street, Edinburgh. Chambers Street came about as one of the major street-planning improvements carried out in the wake of M.O.H. Henry Littlejohn's report of 1855 on sanitary conditions in the Old Town of Edinburgh. Littlejohn urged extensive slum clearance for the sake of public health which was eventually put into effect by the City Improvement Acts of 1867 and 1871. The 70-foot-wide, 1,000-foot-long street, replaced a narrow, squalid thoroughfare running alongside Old College from Adam Square at the eastern end through Argyle Square to Brown Square at the western end. These squares (along with George Square) represented the first major, southwards expansion of the town beyond its traditional boundaries before the New Town was built to the north. All three squares were demolished. The new street was named after Lord Provost William Chambers who was Littlejohn's foremost supporter in pushing for improvements. 1338463
