Mention of Honour in Concrete Structure of the Year 1997 competition: Raippaluoto Bridge

A Mention of Honour was in the Concrete Structure of the Year 1997 competition given to Raippaluoto Bridge built on Mustasaari Island. The Jury complimented both the design of the bridge and its engineering solutions. The bridge piers and pylons form an entity with consistent design. In the Jury’s view, the structural point where the composite beam bridge becomes a cable-stayed construction was a particularly demanding technical detail that had been excellently resolved.

Raippaluoto Bridge was built in harsh conditions by the open sea, which made it necessary to use blast-furnace slag concrete for the castin-place pylons. Despite the difficult conditions, the bridge was completed two months ahead of the schedule, “thanks to good work management and the professionalism of the builders”.

The deck was built from precast slabs, which contributed to the shorter overall schedule. The construction of the bridge, which is 1045 m long in total, started early in the winter of 1995, and the bridge was opened for traffic in August 1997.
