The article presents several possibilities of using tunnels to solve traffic problems in the area of the Polish mountains. So far, in contrast to other countries in Europe and the World in Poland this kind of solution are benefited reluctantly. However, in the longer term, tunnels construction in conjunction with flyovers are cheaper solutions, safer and considerably reduce the negative impact of transport on the environment. The situation is beginning to change and recently in Poland increases interest in the underground construction, particularly tunnels in mountainous areas are observed. This paper describes the newly built tunnel in Laliki and planned to build tunnels in the area of Lubień, Poronin, Krynica-Zdrój, Jordanów and Węgierska Górka.
