Abstract: The present invention relates to a weighbridge consisting at least partially of cast concrete portions, and a method of producing such a bridge. With the object of increasing the accuracy of a weighbridge, of facilitating and cheapening the production of a weighbridge, it is proposed according to the present invention that the bridge (1) should be disposed resting against two beams (5) which are disposed along the long sides of the bridge and supported by transmitter members (6), that at least two transverse beams (7) are disposed secured between the longitudinal beams (5) of the bridge, preferably at the short sides of the bridge, that the cast portions of the bridge are surrounded by an edge lining (3) preferably of sheet metal bearing downwards against the tops of the beams (5, 7), and that the cast portions preferably comprise a corrugated or profiled bottom metal sheet (12) resting substantially against the longitudinal beams of the bridge.
