The private Toronto and Scarboro' Electric Railway, Light and Power Company had operated the single-track Scarboro radial line along Kingston Road to West Hill. When the TTC assumed the route between Queen Street and Victoria Park in 1922, they double-tracked the line and built the return loop at Bingham. In 1927, the TTC took over operation of the Scarboro radial line, which terminated on the east side of Victoria Park Avenue, and connected it to Bingham Loop so that radial cars could be stored at Russell Carhouse. In 1928, the TTC extended the double track east to Birchmount Loop, replacing the Scarboro radial line to that point. Bingham Loop was rebuilt in 1954, with one track removed to accommodate buses as it is today, and streetcar service east of Victoria Park was discontinued.

The tracks at the loop and along Kingston Road were replaced in 2013. The remnants of the old trackage were removed, including a feature which allowed streetcars exiting from Bingham Avenue to turn east on Kingston Road and re-enter the loop.
