This project contains the designing of a precast reinforced concrete bridge on main forest road "Valea Rosie", km 1+110. The bridge will be sized for 2nd category of loading (according to STAS 3221-74) and it will be designed with one lane. The hydraulic capacity was determined after the flow hazard and river geomorphology. .It is necessary to size the main beams of the bridge to support the load, the bending moments and the oblique section of them. The deck size must be calculated to resist its own weight and the layers above it. There are differences between beam and deck design; the load being the common factor design for both. The final phase consists of predimensioning, designing and verification of abutment. The design process ends with determining optimal size in correlation with service the bridge is expected to provide.This project contains the designing of a precast reinforced concrete bridge on the "Valea Rosie" main forest road, km 1+110.
