ABSTRACT
The bridge over the Asón estuary at Treto, is located in kilometer point (KP) 173,800 of the N-634 road, formerly known also E-70, in the North of Spain, and has been continuously inspected and studied in recent years because of its bad general condition and its importance in the regional transportation network road. This bridge presente d significant problem s and the struct ural condition level was critical previously to its intervention in 2015. The rehabilitation proj ect including the restoration of the structural and functional safety level of the structure was deled after material studies and tests were perf ormed. The new updated of the structure from the old nineteenth centuries to the newstandard codes was also performed. This paper analyzes the recen t experience in th e rehabilitation and retrofitting of a singular ro tating steel bridge.
A part from the “green” and safe-security aspects, the intervention took in to account all the social requirements of the population in th e area who recovered the pride in this emblematic and centenarian infrastructure and it is, itself, a successful intervention from the resilient point of view.
