The document discusses a full-scale testing project from 2016-2022 that aims to upgrade the capacity of road bridges in Denmark. The project involves testing existing one-span bridges on-site under increasing loads to determine their actual load capacity. It also involves laboratory testing of new bridge technologies. The next phase of the project from 2022-2026 will expand testing to multi-span bridges, identify stop criteria for overload conditions, develop proof loading guidelines, include international collaboration, and determine the CO2 and economic impacts of bridge upgrades.
