Research of 56 bridge constructions is lead. It is noticed that, overwhelming number of defects which specify insufficient durability of beams, are located on the bridge constructions having in cross-section section 5 or 6 beams. If in cross-section section the greater number of beams (7 and more) defects of durability practically do not meet is located. Defects are revealed: destruction of diaphragms, or associations of diaphragms, vertical cracks in the middle of flight, inclined cracks in basic sections, sagging of beams, skoly concrete in the stretched zone. In the given projects installation of basic parts that causes destruction of basic parts of beams and crossbars is not stipulated. The share of similar bridges on our highways makes approximately 35-40 %. Therefore it is necessary to develop recommendations on ways of repair and reconstruction for the given standard projects in view of growing transport loadings.
