The Kútvölgyi road crossing, the Liptó street and the Lejtő street track will be upgraded.
The Colas, TTDExpert and DUNAGÉP have also been contracted to work on the 56 tramway line, which is well known to hikers and commuters.
As a result of the investment, low-floor CAF trams will also be able to operate on the hűvösvölgy line from autumn.
