In the 1920s, the cars drove from the present pits on "Rue de Laigné" straight into the city, and after a sharp right-hand corner near the river Sarthe Pontlieue bridge (a hairpin permanently removed from the circuit in 1929), before exiting the city again on the rather straight section now named "Avenue Georges Durand" after the race's founder. Then long and unpaved, a bypass within the city shortened the track in 1929, but the city was only bypassed completely in 1932, when the section from the pits via the Dunlop Bridge and the Esses to Tertre Rouge was added. This classic configuration was long and remained almost unaltered even after the 1955 tragedy. Its frighteningly narrow pit straight was further narrowed to make room for the pits and was part of the road itself, without the road becoming wider around the pits, and no separation. The pit straight then was about wide, further widened in 1956 after the tragedy, but the race track and pits were not separated for another 15 years.
