Claims: What is claimed is:

1. A bridge structure of modular elements comprising:

a. a plurality of spaced bases each formed with an upper opening for the insertion of a colum;

b. a plurality of columns formed inserted in each said opening an with horizontal flutings dimensioned for the insertion of cores between said flutings and complementary flutings in the an other components to be fastened to said columns and serving as variable positioning means for horizontal beams

c. a shetled position beam on said column also provided with said complementary flutings and cores as securing means to said column and to road carrying elements

d. said road forming elements being provided with fluted means positioning and securing said element on said beams and on foundations provided with complementary securing means.

2. The structure of claim 1, wherein each base is provided with means such as screws, for the adjustment and alignment of the inserted column;

3. The structure of claim 1, wherein the column is formed with horizontal flutings for the purpose of securing the positioning of other elements;

4. The structure of claim 3, wherein the beams also are provided with flutings dimensioned to receive one side of an inserted core, with the other side of the core being positioned in the respective fluting of the other element to be assembled.

5. The structure of claim 1, wherein the road forming elements are of a semi "U" shape form and are dimensioned to be self supporting structures resting on their respective foundation and forming one complete lane.

6. The structure of claim 1, wherein the road forming elements are self supporting structures made in a semi- "H" shaped form

7. In the bridges structure of claim 1 A surface expansion joint located between road forming elements comprising two interacting assemblies each composed of a plurality of bars mounted with spacing therebetween on a base and wherein the bars of each assembly extend (extending) into the spaces of the opposing assembly.

8. In a expansion joint of claim 7, wherein the parts of the bars extending from one assembly are sliding between the bars and on the base of the opposing assembly.

9. The expansion joint of claim 7, wherein the whole expansion joint is covered with durable and stretchable material.

10. The expansion joint of claim 7, wherein the assemblies have downward openings permitting dirt and other particulars to pass through.

11. The structure of claim 1, wherein the road forming elements are provided with ducts to carry utilities.
