The article discusses the construction of the Rogfast subsea tunnel, which is Europe’s most ambitious engineering project and aims to boost Norway’s transport links and infrastructure. Pursuing difficulties in building an 26.7 km (87.8 mile) underwater tunnel, the project is expected to eliminate a 40-minuteWeekly gap in transporting workers between Stavanger and Bergen, Norway’s largest cities, by 2033 when the project will be completed. The tunnel is part of the E39 highway network and will serve as a direct link, replacing ferry routes. The construction is nearing halfway point.
Key design features: The project features a series of roundabouts under the smallest municipality in Norway, Kvitsøy, which connects to the main tunnel in winter. This design allows traffic to flow even when one lane is closed. Additionally, a twin-tube safety system and green doors are part of the infrastructure.
Construction details: Unlike a modular tunnel (Fehmarn), the Rogfast tunnel is being drilled directly into solid rock, ensuring stability under water pressure. Norway’s expertise in subsea tunnel construction, along with a schedule of 2033, makes it a relatively affordable and durable choice for large-scale infrastructure projects.
