The Port Miami tunnel, a project that has been 30 years in development, was finally completed last month.
The $1bn (£600M) project was built by Miami Access Tunnel, a partnership between Bouygues Travaux Publics of France — a subsidiary of Bouygues Construction — and Meridiam Infrastructure of Luxembourg.
The tunnel has been constructed using a design-build-finance-maintain-operate model.
ArquitectonicaGEO was design architect and landscape architect for support buildings, tunnel entrance structures, tunnel interior finishes and landscaping of tunnel approach roads and support-building campus areas at both ends of the tunnel.
The project includes twin 1.3km-long and 13m diameter tunnels below Miami’s Government Cut shipping channel, connecting Port Miami on Dodge Island with route I-395 via the MacArthur Causeway. There are also just over 100m of approach roads at either end of the tunnel.
