In order to ensure the safety of workers and to reduce the health hazards caused by noise, construction work should be carried out during the day rather than at night. A video has been released explaining the ASTRA Bridge, a mobile construction site bridge developed to allow construction work on busy highways without disrupting traffic.

Simply put, ASTRA Bridge is a system that realizes the concept of 'building a road on top of a road.' ASTRA Bridge is installed wherever you want to pave the road, and cars can pass over the bridge while construction is carried out underneath.
The space under the bridge is 5.1m wide and 3.1m high.
There is enough space to allow construction vehicles to enter without any problems.
ASTRA Bridge is a system in which a number of self-driving tire bridge girders are lined up and a crane is used to lay the road between them. By laying the road at night when there is less traffic, the construction work can be focused on during the day.
The total length is 236m.

Although the ASTRA Bridge construction work itself must be done at night, concentrating the work during the day allows for safer work and frees paving workers from night shifts. In addition, working under the bridge means they are not affected by the weather. At the time of writing, ASTRA Bridge has been used a total of four times to pave roads in Switzerland.
A similar system called 'Miniway' was used in Japan from 1989 to 1999.
