Dismantling of the bridge in Česká lípa

In recent days, we have dismantled the bridge girders in Česká Lípa using a Liebherr LTM 1400 wheeled crane and transported them for disposal as part of the construction – on a Goldhofer telescopic semi-trailer and an Umikov curtain sider. We then used two Liebherr LTR 1100 crawler cranes to unload them. In June, we will be installing new bridge girders here.
Can you guess the weight of such a girder?
