Construction of a waterway connecting the Vistula Lagoon with the Gulf of Gdańsk


Digging of the Vistula Spit

On October 18, 2019, the Maritime Office in Gdynia handed over to the Contractor – a consortium of N.V. Besix SA, NDI S.A. and NDI Sp.z o.o. – the area where works will be carried out as a part of the first stage of construction of a waterway connecting the Vistula Lagoon with the Gulf of Gdańsk. The contract will be implemented over 32 months.
The investment includes the construction of protective harbour from the side of the Gulf of Gdańsk, the construction of a shipping channel with a lock and the construction of closures together with waiting stations from the side of the Gulf of Gdańsk and the Vistula Lagoon, a new road system with movable steel bridges rotating around a vertical axis, which will allow passage over the channel in front of the lock and behind the lock; and the construction of an artificial island located in the Vistula Lagoon. The shipping channel will be 1-kilometre-long and five-metre-deep. Ultimately, it is to enable vessels with a draft of up to 4 metres, length up to 100 metres and width up to 20 metres to enter the port of Elbląg. The construction of the channel through the Vistula Spit is to be completed in 2022. The investor is the Maritime Office in Gdynia. The implementation time from the date of signing the contract is 32 months. The investment is located within two voivodeships – Pomeranian Voivodeship and Warmian-Masurian Voivodeship. The following elements of the project are located within the borders of the Pomeranian Voivodeship, in the Sztutowo and Krynica Morska commune: the construction of a shipping channel through the Vistula Spit, the construction of a waterway in the northern part of the Vistula Lagoon (the border of the voivodeships passes through the centre of the Vistula Lagoon) and the construction of an artificial island. Within the borders of the Warmian-Masurian Voivodeship, the southern part of the waterway in the Vistula Lagoon is located in the commune of Tolkmicko, and the waterway on the Elbląg River with adjacent land areas are located within the Elbląg commune and the city of Elbląg.
