The western part has several lanes and the eastern part is a city street, while the rest of the route is a major road that is used as access to Kallirois Street which links with Vouliagmenis Avenue as well as Vasileos Konstantinou Avenue, thus linking the western suburbs of Athens to the southern ones, bypassing the downtown section.
Construction began on an underpass when traffic increased on Lenorman Avenue in the mid-20th century.
Later in the mid to late 20th century, construction began on an overpass with Petrou Ralli Avenue and a junction in the northwestern section.
It lasted for about a year when an overpass was built with an Athens-bound exit and a westbound entrance and the road was finally re-opened.
The northern part ran through the railway crossings while the avenue link runs below.
