Czech Transport Construction of the Year 2010
Prague City Ring Road, Lot 513
Libor Mařík
The southern section (Lot 513: Vestec - Lahovice) of the Prague City Ring Road passes across Vltava and Berounka Rivers valley and then it ascends, heading to Cholupice. The designed alignment requires the construction of new tunnels. The route leads firstly through 70m long cut-and-cover tunnel and then, after short opencut section, passes into driven tunnel of almost 2km total length. Both tunnels are designed as twin-tube structures. Project included design of portal pits, cut-and-cover and driven tunnel sections, covered tunnel, stormwater sewage shaft and adit, ventilation shaft and M&E objects on both portals.
