The object of the project is the construction of the D3 motorway category D 27,5/120 in the section 0309/III Borek – Úsilné with a total length of 3.160 km conducted on a completely new route, including completion of the off-level junction Úsilné. The implementation of the construction will mainly reduce the traffic burden on the existing road I/3 in the municipality of Borek and the following parts of the town České Budějovice. This will reduce the burden on the population by noise and exhalation from car traffic, increase traffic flow and reduce traffic accidents.
