ARNHEM, The Netherlands--(BUSINESS WIRE)--March 31, 2004

ARCADIS (NASDAQ: ARCAF, EURONEXT: ARCAD), the international consultancy and engineering company, today announced that it has been selected as part of a consortium that will design and execute the project management for a high-speed rail track and tunnel through the Pyrenees between France and Spain. Along with ARCADIS, the consortium also consists of specialists from INGEROP (France), SENER (Spain) and TUCRAIL (Belgium). The project includes both a track for public transportation as well as for freight trains. The new rail connection will shorten the travel time between Perpignan (France) and Figueras (Spain) by two hours. The total cost of the project amounts to EUR 952 million. The revenue for ARCADIS will amount to EUR 6 million.

The project will consist of building a double track over land and two single tracks through two separate tunnels. The latter is done for safety reasons. The track will be more than 44 km in length and the first trains are expected to run in 2009.

The building of the new track between France and Spain is a major step in improving the connection between the two countries. Currently, the mountains of the eastern Pyrenees and the differences between the two rail systems are major hurdles. As a consequence, much of the traffic is going via the highway, often resulting in large traffic jams.

"ARCADIS is proud of this important assignment," said Harrie Noy, Chief Executive Officer of ARCADIS. "For years now, the French and Spanish have been discussing ways to improve accessibility. It is apparent that a high-speed train connection through the Pyrenees will be an advantage. This is an excellent example of investments being made in transnational European networks. Our extensive know-how and experience in rail-infrastructure and bridges and tunnels, combined with our strong positions in our home markets, make us excellent partners for this project."
