Assessment of Masonry Arch Bridge with Concrete Deck

The assessment of a masonry arch bridge, built more than 110 years ago and widened twice with concrete decks during it service life, is presented in this paper. Conservative methods for the assessment of the load-carrying capacity of masonry arch bridges are shortly overviewed. Additionally the bridge deck cantilever is evaluated due to the bad condition of the second widening deck, taking into account the possibility of vehicle impact on the guardrail. Results are discussed and the deck cantilever replacement with the adequate new reinforcement is proposed.
