The Strahov Tunnel reigns over Prague's road tunnels with its length

Vyšehrad Tunnel - the oldest and shortest:
The oldest road tunnel in Prague is the 35-meter-long Vyšehrad Tunnel. It was built between 1902 and 1905 and runs through a rocky massif connecting Rašín's and Podolí's embankments. It is the only one serving both tram and car traffic.

Letná Tunnel:
The Letná Tunnel, construction of which began in September 1949, is 426 meters long and overcomes a height difference of 23 meters. As part of the civil defense system, it was connected to the adjacent shelters under Letná. In 2002, it was damaged by floods and closed for several months.

Strahov Tunnel - the longest in the Czech Republic:
One of the most modern tunnels, connecting Smíchov and Dejvice. Its construction began in 1986 and was completed in 1997. It measures two kilometers, and at high traffic volumes, up to 43,000 vehicles pass through it per hour.

Těšnov Tunnel:
The 350-meter-long Těšnov Tunnel connects the embankments of Ludvík Svoboda and Rohanská in Prague. It was built between 1977 and 1980 with the aim of calming the area in front of the former Central Committee of the Communist Party of Czechoslovakia (now the Ministry of Transport and Communications). Therefore, it was nicknamed "Husák's Silence."

Mrázovka Tunnel - the newest:
In August 2004, the Mrázovka road tunnel, connecting part of the city ring road from Zlíchov and Radlická street to the Strahov Tunnel, was opened in Smíchov. The excavation of the approximately one-kilometer-long tunnel began at the end of 1998. It was supposed to be completed in September 2001, but construction was complicated by protests from environmental activists. Originally, the tunnel was to cost 4.5 billion crowns, eventually its price soared to seven billion.

Zlíchov Tunnel:
In October 2002, the section of the city ring road Zlíchov-Radlická was opened, which includes a 165-meter-long tunnel. To the north, it connects to the Dobříšská road leading into the Mrázovka Tunnel, and to the south, it connects to the ramp leading to the Barrandov Bridge.

Lochkov - Radotín:
Currently, work continues on a road tunnel between Lochkov and Radotín in Prague. The approximately 1.6-kilometer-long tunnel will be part of the outer ring road section from Slivenec to Lahovice and is expected to be fully completed by September 2009.

Blanka Tunnel Complex - to be the longest in the Czech Republic upon completion:
The 5.5-kilometer-long Blanka Tunnel Complex, which will run under Letná and Stromovka, will be part of the northwestern section of the city ring road. The costs of its construction exceed 20 billion crowns, and it should be completed in 2011.
