Just over 300km of national roads – one in every 18km – is exposed to future flooding under the current outlook for climate change. Some of the newest stretches of national road may also need attention. Coastal flooding is not a big concern as little of the national road network is close to the sea but some stretches are. “The asset value of the national roads network is approximately €31 billion,” he said. “Almost €800 million was allocated for national roads this year.”While most of that will be spent on new road projects, the figure “includes funding to protect and renew the existing national road network, which will better enable it to withstand severe weather events”.
