The continuous increase of traffic loads lead to rising fatigue stresses and to a reduction of the remaining service life of existing, aged bridge structures. Many of these bridges are not designed for the expected fatigue stresses; thereby, the monitoring of these bridges becomes an economic as well as safety relevant aspect in civil engineering. This paper describes traffic census and load measurements on a box girder bridge by structural and geodetic measurements. The structural measurements are primarily performed by strain gauges and displacement transducers. The algorithms of the detection of passing heavy goods vehicles and of the identification of their total vehicle weights and axle loads will be presented. The geodetic measurements are carried out by a terrestrial laser scanner. The deflections of the bottom slab are measured and the corresponding strains are obtained. Geodetic and structural measurement results will be compared.
