Inland waterways transport accounts for 6.3% of freight volume in the EU, with some countries that have extensive waterway infrastructure having higher shares. Some of Europe's largest seaports use inland waterways to transport freight due to increasing congestion and lack of rail capacity, with 70% of EU trade going through seaports. The availability of waterways provides a competitive advantage, such as avoiding 100,000 truck movements daily in Rotterdam. Investing in inland waterway infrastructure can help absorb major freight flows between seaports and inland economic centers, making road traffic less congested and providing an efficient transportation option.
