Abstract: 1. Guideway girder(2), in particular for a magnetic levitation transport system (100), for forming a guideway with a number of girders (2) that are successively assembled in the direction of travel, with an upper girder section (12), in particular a top chord (12), possibly with a lower girder section (15), in particular a bottom chord (15) and at least one supporting section (13,14), in particular a web (13,14) below the upper girder section (12), characterized by at least one sound insulation element (7,8) located in the area of the upper girder section (12) and/or of the lower girder section (15) and/or of the (at least one) supporting section (13,14). 2. Guideway girder as in claim 1, characterized by a hollow cross-sectional configuration, whereby the cavity (16) is delimited toward the top by the upper girder section (12), laterally by a supporting section (13,14) on either side and toward the bottom by a lower girder section (15). 3. Guideway girder as in claim 1 or 2, characterized by an installation on one or several pillars (5) imbedded in the ground. 4. Guideway girder as in one of the preceding claims, characterized in that the faces of the supporting sections (13,14) of two girders (2) following each other successively in the direction of the guideway and which are across from each other are essentially connected to each other. 5. Guideway girder as in one of the preceding claims, characterized in that sound insulation elements (7,8) are installed on the inside and/or outside of the supporting sections (13,14), on the bottom and/or top of the upper girder section (12) and/or on the top of a lower girder section (15). 6. Guideway girder as in one of the preceding claims, characterized in that the (at least one) sound insulation element (7,8) is essentially flat in shape and at least partially covers in the manner of a lining the (at least one) supporting section (13,14), the (at least one) upper girder section (12) and/or the lower girder section (15). 7. Guideway girder as in one of the preceding claims, characterized in that at least one sound insulation element (8) is provided with two flat segments (8a, 8b) that are at an angle to each other. 8. Guideway as in one of the preceding claims, characterized in that several sound insulation elements (7,8) are installed one next to the other in the direction of travel. 9. Guideway girder as in one of the preceding claims, characterized by a design as a bivalent guideway, e.g., for magnetic levitation transport trains as well as for conventional trains. 10. Utilization of a tabular sound insulation element for installation on a guideway girder (2) installed or that can be installed essentially above ground, with an upper girder section (12), possibly a lower girder section (15) and with at least one supporting section (13,14), in particular a guideway girder (2) as in one of the previous claims. 11. Utilization of a sound insulation element as in claim 10, characterized in that it is used to line free surfaces of the (at least one) supporting section (13,14), of the upper girder section (12), and/or of the lower girder section (15). 12. Utilization of a sound insulation element as in claim 10 or 11, characterized in that in addition advertising elements are attached to the sound insulation elements (7,8), in particular billboards and/or illuminated publicity.
