The purpose of the project is to restore and improve the transport performance and the load bearing capacity of the pavement, in order to provide conditions for road safety and good drainage of the road. Complete geodesy and geological measurements have been prepared for the project, as well as projects for environmental protection and safe working conditions during construction.
The detail design project concerns major overhaul of an existing river bridge, rehabilitation of an existing bridge over the river, a new traffic organization and the displacement of existing engineering networks within the crossing.
