Some efficient solutions for bridge reconstruction

Sometimes, bridges have to be reconstructed because of the various causes as their age, great deteriorations, new operation conditions so on. In many cases, to reconstruct a bridge is more difficult than to construct a new one. Many solutions have to be analyzed in order to find the best one. That means to solve the reconstruction problem in the best quality conditions with the minimum cost. Such solutions are based sometimes on well inspired ideas that have just to be put in practice. The paper presents three cases of bridge reconstruction where interesting solutions based on excellent ideas were applied, so saving a lot of money.
