During the construction of metro D in the section between Pankrác and Olbrachtová, the workers have to break through tens of meters of the tunnel connecting route D with line C and the parking tunnel. In one part, they are still finishing the excavation of the tunnel to its final size. The minting will then also continue in the stations. Now the builders are working on the insulation in the so-called secondary lining of the already excavated buildings of metro D. The construction pit for the construction of the transition between the shopping center and the Pankrác D station is complete.
The construction of line D from Pankrác to Písnice began in 2022 with the section just mentioned between Pankrác and Olbrachtova stations, which will cost 14.5 billion CZK. It will be followed by a section from Olbrachtova to Nové Dvory, where the tender for a contractor is being assessed by the Office for the Protection of Economic Competition.
“Almost all track tunnels between the named stations have been dug except for the single-track connector between routes D and C, where the last 55 meters are missing, its total length is 468 meters, and the entire single-track parking tunnel with a length of 157 meters. The contractors will start both of these tunnels by the end of August this year.” said the spokesperson of the transport company Daniel Sabík.
At the end of the summer, construction workers will break through a tunnel from the junction between lines C and D to the Pankrác C station, to the place where a niche was already created in the 1970s for a future connection to another metro line. In one short section, workers are still finishing the excavation of the so-called full profile double-track interstation tunnel.

It is exactly one year since the construction of the first section of metro line D from Pankrác to Olbrachtova station began. During that time, the workers broke through over a kilometer of new tunnels and extracted over 67,000 cubic meters of stone and earth. The entire line up to the Písnice Depot…
Excavations will continue at the stations themselves. At Pankrác D, about 40 percent are now minted, and in Olbrachtov it is about 52 percent of the station. The builders have already started the excavation of the escalator tunnels from the Pankrác D station to the Gemini building and the escalator tunnel from the construction pit at the Arkády Shopping Center, which will be used to exit the station directly into the shopping center. “After two years of construction of metro D, 2,340 meters of tunnels and tunnels are excavated. The volume of mintages is 70 percent of the total volume,” said Šabík.
Workers make insulation and secondary cladding of stamped objects. They were the first to complete it in the air conditioning machine room tunnel between Pankrác D and Olbrachtova stations. In the left track tunnel and the adjacent part of the station tunnel of the Olbrachtova station, only after the North jumper, the bottom vault is completely concreted. At the Olbrachtova station, 36 of the 213-meter-long upper vaults have been completed in the left station tunnel.
“The work on the surface is most visible in front of OC Arkády, where the construction pit for the construction of the transfer between the shopping center and the Pankrác D station is ready. said Šabík. At the construction site of the Olbrachtova station in Na Strži Street, builders are now digging construction pits for the southern and northern vestibules, from where excavation of the escalator tunnels will begin this year.
