ABSTRACT
This paper presents a summary of the service life of The Tjörn Bridge. The focus is highlighting deviations of the expected maintenance, replacements, and upgrades from the expected service life of the bridge. The objective is to identify the bridge components and operational conditions, which often may be deviating from the expected planned service life in connection with the design of a bridge. The Tjörn Bridge being a 366 m span cable stay bridge from 1981 has reached an age where maintenance tasks have started to increase. Some tasks, such as general degradation of paint, pavement, joints etc., have been in line with expectations, whereas other have been unexpected and thus called for mitigation. The Tjörn Bridge was constructed over a record short duration of 18 months as it replaced the old bridge which collapsed due to a ship collision.
