The beltway runs north to south from Gdynia to Pruszcz Gdański and is 38.6 km (24.0 mi) long.

The various stages were constructed in the following years: The beltway is an important piece of infrastructure in the Pomeranian Voivodeship easing congestion through the center of the Tricity area and diverting transit traffic.

Eugeniusza Kwiatkowskiego was completed and finally connected the Port of Gdynia to the beltway, bypassing the local city streets.

A new beltway called the Tricity Metropolitan Ring Road is being planned further out, after multiple delays scheduled for 2025, and the route of the S6 expressway is to be moved there once it is opened.
