D4 motorway (Czech Republic)
The D4 motorway is a Czech motorway running from Prague via Příbram to Nová Hospoda, where it connects to road I/20.[1] It links Prague with South Bohemia.[2]*
Construction
Construction began in the 1960s. The first section opened was the Zbraslav bypass, on 1 December 1966. The motorway reached Příbram in 1989.[1] The Nová Hospoda junction opened in 2007, and the 6.7 km Mirotice – Třebkov section in September 2010.[1]
The Příbram – Písek section
The missing section between Příbram and Písek was the first transport project in the Czech Republic built through cooperation between the private and public sectors (PPP).[3] Construction started on 7 June 2021.[1] It took 43 months and was carried out by the VINCI Construction CS group. It produced 32 km of new motorway and modernised 16 km of older sections. Traffic began on 17 December 2024.[2] The company Via Salis will operate and maintain the section for 25 years. The state will pay it 17.8 billion crowns and take over the motorway in 2049.[3] The journey between Prague and Písek was expected to become at least 20 minutes shorter. The whole D4 is monitored by 193 cameras.[3]
