The A 3 passes through a largely forested area until Aschaffenburg, passing the city of Frankfurt am Main proper to the south with eight lanes; the Frankfurt-Süd junction, which is located near the Commerzbank-Arena, is the only direct link with Frankfurt. It intersects with A 661 near Offenbach, continuing from this point as six lanes towards Offenbach am Main, Hanau and Seligenstadt, which are also connected with one interchange. As the A 3 enters Bavaria, it intersects with the A 45, crossing the Main on the Mainbrücke Stockstadt and Aschaffenburg and the suburbs Goldbach and Hösbach.
