The world's first ship tunnel could enter the construction phase in Norway in two years.

A feasibility study is to be presented by the Norwegian Coastal Administration (NCA) to the ministry of transport in May, according to Business Insider.

Project manager Terje Andreassen told the website the project would need to be fully financed by parliament, which has already set aside NOK 1bn (117m) for NCA's research.

If the plans are approved, construction could start as early as 2019, Andreassen added.

The Stad Ship Tunnel could see between 70 and 120 vessels transiting per day.
