Project:
Queen Máxima Bridge, Alphen aan den Rijn

On order of the contractor Mobilis-TBI, Spanbeton produced and delivered the 147 prefab ZIP-beams for the Queen Maxima Bridge in Alphen aan den Rijn.
The bridge consists of 7 spans of about 25 metres and a movable bascule section to allow ships to pass.
Spanbeton played an advisory role in this project in two ways: firstly, Spanbeton offers a sustainable alternative for the top side of the deck, which is oriented in a transverse slope. This slope drains rainwater to the sides of the bridge. A lot of material is needed to achieve this slope. The solution offered saved about 100 cubic metres of concrete. This is in keeping with the sustainability pillar within the tender. On one side of the bridge, beams 900 millimetres high were used, and 1000 millimetre beams on the other side.
It was also decided to use a construction with wet joints. This is a joint made of concrete and reinforcement that is cast in place between the prefab deck and the columns. This connection replaces the transverse beam that usually provides support. This method creates a bridge deck with internal pillar beams that spread the bridge deck load over the columns. The advantage is that this makes the underside flat, which gives the bridge a transparent character. “With the application of wet joints, Spanbeton’s technical expertise was indispensable,” says Rens Olij, project leader at Mobilis-TBI. “Spanbeton joined the discussion at an early stage with the concrete engineer to talk about the details regarding reinforcement and force transfer

With the completion of the Queen Maxima Bridge, the traffic is diverted from the city centre of Alphen aan den Rijn, which improves the liveability for the residents. The bridge also provides access for heavy cargo traffic to and from the Hoogewaard industrial park. This provides greater mobility for the companies there, including Spanbeton.

TBI company Mobilis and its partners Aannemingsmaatschappij Van Gelder and Hollandia Infra built the Queen Máxima Bridge on order of the Municipality of Alphen aan den Rijn. The last prefab beams were installed in the middle of April 2016. The bridge was fully operational at the end of 2016.
