ViaCon helps reinforce existing highway underpass without disrupting local traffic.
The Challenge
An underpass under German highway 45, connecting two villages, no longer met requirements and needed rehabilitation.
The Solution
The plan for renewal included a new corrugated steel structure assembled in front of the existing bridge, which was then pulled into the existing bridge.
Due to the total weight of about 160 tonnes, the transfer tracks were equipped with Teflon rails to reduce friction. As a result, a relatively small vehicle was sufficient to pull the corrugated steel structure.
After completion of the assembly, the remaining space between the old and the new bridge structure was filled in stages so that the corrugated steel structure could withstand the traffic load.
