Zusammenfassung:	The utility model discloses a combined pipeline road-crossing protection bridge, comprising multiple protection blocks. Sectional areas of the protection blocks are arched, and have bridge openings which are radial through holes. Side end faces of the protection blocks are provided with dovetail blocks and dovetail grooves which are corresponding to each other. The multiple protection blocks can be connected to form the protection bridge with a desired length via the dovetail blocks and the dovetail grooves. The utility model has the beneficial effects that the combined pipeline road-crossing protection bridge enables to embed water pipes, cables and other pipelines which need to cross the road in the bridge openings which are radial through holes, so that water pipes, cables and other pipelines are prevented from being rolled by wheels and therefore are effectively protected.
