Andrea Syngrou Avenue is an important road in Athens, linking Poseidonos Avenue with the centre and other avenues. It is planned, built and later named for Andreas Syngros. It runs southwest to northeast, with a speed limit of 90km/h. The Syngrou-Fix station of the Attiko Metro's Red Line is situated at the northeastern end of the avenue. The avenue also has shops and stores mainly 4 to 8 story buildings by its one-way service road of the same name.
The avenue passes between the municipalities of Palaio Faliro, Kallithea and Nea Smyrni as well as Athens, and has about four to five interchanges. It is the only avenue in Athens to resemble a motorway, since it has no traffic lights, except of course when it reaches the city centre.
