The shopping centre consists of three floors with over 110 businesses, cafés and restaurants with a total shopping area of 30 thousand square metres. There are about 880 for-pay parking spaces on two floors. Two prevent traffic congestion, St. Veiter Ring was widened to four lanes in the area around City-Arkaden. Directly in front of the main entrance is the bus stop "Heuplatz" where the Klagenfurt city buses 40 and 41 stop every 7 to 15 minutes in directions of the Klagenfurt railway station, Annabichl and Feschnig. Of the businesses in City-Arkaden, 40 opened their first premises in Carinthia in the centre, 15 of them even their first premises in Austria.
