Deepening the fairway Świnoujście-Szczecin to a depth of 12.5 m will improve access to the port of Szczecin from the sea. Larger vessels will be able to call at the port of Szczecin and thus the current trends in cargo turnover will probably change. To make it possible, it is also necessary to invest in improving port access from the mainland. In the article the authors present estimates and forecasts of the annual average daily traffic of vehicles (AADT) on national road no. 10 (DK 10) and access roads to the port of Szczecin (so called the "last mile" sections). Estimation was based on the author's own traffic research carried out in September-October 2016 as part of Feasibility Study for the project Modernization of the access roads to the port o/Szczecin: reconstruction of the transport system in the area of Miedzyodrze implemented by the city of Szczecin.
