Risks of rutting and blow-ups of roads  due to high summer temperatures are expected to increase in WCE and EEU at 3ºC GWL  . In EEU and northern Scandinavia, the higher number of freezing-thawing cycles of construction materials will increase risks for roads , while warming beyond 2ºC GWL could significantly reduce road maintenance costs in NEU , but limit off-road overland transport in northwest Russia . Beyond 3ºC GWL, more frequent hourly precipitation extremes are projected over WCE and NEU in summer  but more widely across Europe in autumn and winter , potentially severely damaging roads as happened in Mandra, Greece, in 2017 . Landslide risks in WCE and SEU could increase beyond a 2°C GWL, threatening road networks .
