Switzerland engineers have developed a revolutionary mobile overpass named 'ASTRA Bridge'. This technology has the ability to completely eliminate the problem of long traffic jams that occur during road construction and repair。
The main features of this bridge are as follows:
Continuous traffic flow: This 257-m-long mobile bridge is installed above the construction site, allowing vehicles to pass above it at 60 km/h speed, while employees below continue to repair the road.
Safety: It directly separates workers from traffic, reducing the risk of accidents and they are also safe from noise, sun or rain.
Easy Transfer: It's a modular design that can be assembled at night through trucks. As road work progresses, this bridge can be moved forward with the help of hydraulic systems.
Used: It has been successfully tested on Switzerland's busiest A1 highway.
