The metro D in Prague would begin with the construction of the section between Pankrác to Olbrachtová.
The reason for that section to be given priority is the relative ease of buying the required plots of land. The route would later be continued south in the direction of Pisníce. Another section should connect Pankrác with the center of the city and Náměsti Míru.
The cost of the new metro line is estimated at Kč 50 billion and will in part use EU funds.
The Metro D line would be the first completely new line since Metro B, which opened in 1985.
More information about the project (in Czech), along with visualizations for each of the new stations, can be found DPP’s “new metro” website.
