The object of the project is the construction of the section bypass Mariánské Lázně and modernisation of the part of road II/230, which aims to increase safety and comfort of road traffic. The construction ensures a new connection of the proposed route I/21 (not part of this construction) with existing roads II/230 and III/211 4 at the junction near Mariánské Lázně. The proposed route will divert transit transport from Mariánské Lázně and thus allow a safe and capacitive transfer of transport loads in this location.
