The subject of the project is the construction of the relocation of the I/9 road in the total length of the main route 1.451 km in category S 11.5/90, which is designed as part of the western bypass of Česká Lípa. The implementation of the project will divert transit traffic outside residential buildings and reduce the burden on the population by noise and exhalations. There will also be an increase in traffic flow on the I/9 road, a reduction in driving time and an increase in road safety in Česká Lípa, including pedestrian safety.
