Szukana fraza: [Abstrakt = "The south ring of Poznań constitutes a part of the motorway A2 between the intersections Poznań\-West and Poznań\-Krzesiny. The motorway A2 is always busy around Poznań\: between these two intersections more than 45 000 vehicles drive throughout the day and night, and between the intersections Komorniki and Luboń, which is a part of the previous ones, even more ─ over 60 000 vehicles. Since November 2017 a speed limit of 120 km\/h is in force on the south ring and also overtaking by lorries is prohibited there. Within a short time, in the spring of 2019 an upgrade of the south ring of Poznań is to begin. The upgrade will consist in extending the motorway A2 by the third traffic lanes within a year and half. On this occasion it is worthy to look at the construction and the current technical state of the bridge structures over the motorway, whose technical \(geometrical\) parameters are a source of serious problems for its upgrading. The subject of our interest are the overpasses over the motorway at the intersection Poznań\-Krzesiny. After a local inspection in April 2018 we can say that both the overpasses are in a good technical condition. The aim of our analysis of the technical parameters of the overpasses is to present some hints about the design of similar structural objects in the future. In particular, it is about a wider space under overpasses, greater length and width of the overpasses themselves and better placement of their supports, accounting for the unavoidable upgrading in the future."]
