If the council material is approved, they will send their opinion to the Directorate of Roads and Motorways (ŘSD), which is preparing the construction of the circuit. According to current plans, the Prague ring road is to measure over 80 kilometers, and about half of it is in operation.
The original design of the route of the section designated 520 from 2009 took into account that the road would run on the surface. Based on discussions with the town halls and the city, in addition to the original solution proposal, two other variants were subsequently developed. They all have the same route, but the new two differ from the original just by the excavation or construction of tunnels.
The sunken variant means that, wherever possible, the road would lead underground, on average up to eight meters. The Třeboradice flyover would then be reduced by as much as 17 meters.
The third variant, in addition to the excavation, proposes the construction of three tunnels, namely Vinoř with a length of 1.3 kilometers, Veleň, which would measure 450 meters, and Třeboradice with a length of two kilometers. It is not clear which variant will be selected in the end.
According to current plans, the outer Prague ring road should measure about 83 kilometers, and about half of it is now in operation. The section from the Brno D1 motorway to Běchovice is missing, as is the entire northern part from Ruzyně via Suchdol, Březiněves to Černý Most. Radials, which are roads that are supposed to connect with the inner city ring road, which is building Prague, have not been completed either. The town halls in the north of the capital have long been fighting against the current route of the Prague Ring Road.
