For a nation of trucks loaded with grain, sturdy concrete roads represent the path to the future, promised participants yesterday at a Concrete Roads conference in Kyiv. Noting that concrete roads hold up in the summer heat, while asphalt roads sag, Infrastructure Minister Vladyslav Krikliy vowed to raise the percent of main roads built with concrete from 1% today to 30% in 2040. As leaders of Ukraine’s cement industry nodded appreciatively, Rada Member Olena Shulyak vowed to spend $700 million a year through 2025 to build concrete roads.
