The roads are the main tool for business and economic development of a region. Bridges failures generate the interruption in the normal traffic, producing many and incalculable losses while the normal traffic is restored. Antioquia is one of the longest road networks in Colombia with several numbers of bridges that conform its road infrastructure assets. Many of these bridges have not been properly maintained since its construction, which can cause structural failures and even its possible collapse. The inventory bridges made in every departmental road in Antioquia identified the main physical parameters of the bridge, the building type, the type of structure and the current level of damage. The inventory showed that reinforced concrete is the most common structural type used in bridges, with most common length between 5m and 10m, inventory also showed that 11 % of the bridges require immediately intervention due to several damages in their structure and 48 % of them are working properly.

Keywords : Bridges; Roads; Infrastructure; Antioquia.
