D1 motorway between the cities of Prague and Brno is around 200 km long and is the oldest in the Czech Republic with its first sections being build from 1967 till 1980. The motorway has been undergoing a total refurbishment over the past few years. The works are divided into 25 sections and 25 contracts. New green bridges are being build on some sections. We are currently working on such a new bridge in km92. More details can be found in the attached video.
