Troost Avenue is a major street that stretches north to south in Kansas City, Missouri. The development of Troost avenue began in the year of 1834 near 31st Street and the street continued to develop into the 1900s, introducing movie theaters, apartments, retail stores and more. Troost avenue is also historically known as a racial dividing line in Kansas City. My research was over Brush Creek BLVD and 43rd street along Troost avenue. It has a few changes overtime for example, It went from grid setting into more commercial place and the grids begin to dense with businesses and residents. Business like Cars & Auto were more dominant in the period of 1909 to 1950 but eventually it started to decrease in those businesses. Shopping business like CVS, Dollar tree were introduced as well as bus transportation system like RideKC and Max in the present time but it is still is a dividing residential place between high incomes and low income.
