Utrecht | A27 | Lunetten

This 140-meter-long traffic viaduct over the A27 is equipped with FiberCore composite bridge decks. The deck is made up of seven parts and has already been connected to the steel structure at the construction site. The finished construction was then placed in its entirety over the A27 motorway.

The enormous weight saving was the guiding principle in the choice of a composite deck, in hybrid with the steel construction. The much longer lifespan and maintenance-free character of the deck also played a role. The viaduct was built on behalf of ProRail, Heijmans was the main contractor.
