Marti was one of the contractors involved in the Astra Bridge, which is a bridge that can be installed over a motorway, such that roadworks can be carried out under the bridge while there is uninterrupted two lane traffic right above them.[14] This type of construction was the first of its kind.[15] The bridge has a modular design, its parts can be carried by regular trucks and it can be installed in a matter of days.[16]
Controversies
In 2020, Marti was accused that their handling of construction waste resulted in fish deaths in the Blausee since 2018.[17] Marti denied the accusation, saying that what they did was allowed by the authorities and it was not the cause of the fish deaths. As of 2024[update] the case is pending in Swiss federal court.[18]
