Read this: Like most Dutch cities, Utrecht has an extensive network of cycle paths, making cycling safe and popular. 33% of journeys within the city are by bicycle, more than any other mode of transport. (Cars, for example, account for 30% of trips). Bicycles are used by young and old people, and by individuals and families. They are mostly traditional, upright, steel-framed bicycles, with few or no gears. There are also barrow bikes, for carrying shopping or small children. As thousands of bicycles are parked haphazardly in town, creating an eyesore but also impeding pedestrians, the City Council decided in 2014 to build the world's largest bicycle parking station, near the Central Railway Station. This 3-floor construction will cost an estimated 48 million Euro and will hold 12,500 bicycles. Completion is foreseen in 2018.
