During their service life, faults and deficiencies that influece their functionality and appearance emerge on bridges. In order to ensure safety, usability and aesthetic appearance, structures have to undergo regular expert review and maintenance. Some bridges are damaged to the extent where it is necessary to consider alternative solutions. This thesis compares solutions to the bridge over Ozlenšček in Ozeljan. In the first step, we compile an inventory of necessary remedial works on the basis of the examination and tests on the bridge and calculate the estimated costs of comprehensive rehabilitation. These costs are later compared with estimated costs of the newly constucted bridge. The results show that the cost of the replacement construction is almost 15 times grater than the cost of the rehabilitation, therefore we select the latter as a more rational and economical solution. In addition to the comparison of cost, other criteria such as sustainability and usability are used.
