What does the rehabilitation of bridges focus on besides structural integrity?

The rehabilitation of bridges goes beyond merely ensuring structural integrity; it also aims to maintain the bridge's usability over time. This involves making sure that the bridge can continue to handle the traffic volumes and types for which it was originally designed or possibly adapt to new requirements.

Maintaining the bridge's use means functioning safely and effectively for vehicles and pedestrians, thereby extending its service life and ensuring it meets current safety standards. Other options like increasing the width, aesthetic upgrades, or implementing new traffic signals might be considered in specific projects, but they are not primary focuses of bridge rehabilitation aimed at prolonging usability. The essential goal is to ensure that the existing structure remains functional and can be safely used by the public, which is key to a successful rehabilitation project.
