The new type of engineering constructions that is mobile overpasses is developed. The offered mobile overpasses are applied for elimination the arisen traffic jams along city highways, when repairing city municipal networks, during emergency situations, etc. They allow to carry out continuous movement of motor transport through various obstacles: traffic jams, ditches and trenches formed because of underground repair work or emergency situations (earthquakes, floods, etc.). The issues of development theoretical bases of calculation and design of mobile overpasses are considered.
