[column]Major maintenance will begin on “De Hef” in 2014. The bridge dates from 1878 and has been completely repainted as many as 9 times during its existence. Meanwhile, the thickness of the paint layers in many places exceeds 2,000 µm. This is no longer a good basis for applying new layers of paint. It is expected that the entire bridge will have to be blasted bare. [/column]
