Road congestion in the Netherlands has worsened since the economic recovery and has risen 10% over the past six months, motoring organisation ANWB said on Thursday.

The problem is particularly acute in and around Amsterdam where congestion – the length of jams multiplied by their duration – has gone up 49% compared with the same period in 2015, the ANWB said.

Over the country as a whole, morning rush hour congestion has increased by 12% and in the evening by 5%. But during the day, congestion is up 20% in total.

Pressure has been reduced around Rotterdam with the opening of the A4 between Delft and Schiedam and the expansion of the A15.
