"Today we are opening the most modern and at the same time longest tunnel in Poland," Mateusz Morawiecki told a news conference.
He said the new 2,335-metre tunnel would help connect the western and eastern parts of the country and become a key component of its expanding network of expressways and highways.
Morawiecki voiced hope the project would contribute to the country's economic development and help improve quality of life for residents in Warsaw and its region as well as the country as a whole.
He also told reporters that "hundreds of kilometres of new roads" would be built across the country during the next few years to "enhance the comfort of Polish drivers, improve road safety and further boost the country's economic development prospects."

In December last year, Morawiecki launched a new bridge and a new stretch of road making up part of the city’s southern beltway.
He said at the time that the massive road project was one of the biggest in the country's modern history.
The entire project carries a price tag of around PLN 4.6 billion (EUR 1 billion, USD 1.25 billion), including almost PLN 1.7 billion in European Union funds, the PAP news agency reported.
