New section of highway in Silesia brings major transport corridor a step closer to completion

The cross-regional Drogowa Trasa Średnicowa (DTŚ) highroad between Katowice and Gliwice is one of the most important east-west transport corridors in Silesia as well as being the largest road investment ever made by local government in Poland.

When finally completed, the six-carriageway highway will have a total length of 31 km of which around 20 km has so far been constructed between Katowice and Zabrze. For planning reasons the remaining 11 km western section, between Zabrze and Gliwice, has been divided into two separate projects: the current project of 5.75 km and a final stage of 5.25 km.

The DTŚ highway is one of the most important roads in the Upper Silesian Industrial Region and runs, for most its course, parallel to the A4 motorway. Because it is situated further northwards, the DTŚ, unlike the motorway, provides better access to the congested city and town centres of the Upper Silesian Metropolitan Union. The final section of the highway to Gliwice will include connections to the east-west A4 motorway as well as to the north-south A1 motorway. The road is the main toll-free alternative to the tolled A4 motorway and is expected to be used mostly for local and regional traffic but also by some transit traffic.

Built with the environment in mind

The highway extension will include road interchanges, paths for pedestrians and cyclists, road safety and traffic management features as well as acoustic screens and other environmental protection measures. In Gliwice, the route of the road crosses polder land where an elevated section of road will have to be built. In the woodlands near Zabrze, the road has been designed to allow animals to migrate under an overpass.

The purpose of the road extension is to improve traffic flow, capacity and journey quality. It is calculated that the completed highway will eventually shorten the road distance between Katowice and Gliwice by 26%, reduce travel time by 76% and reduce petrol consumption by 47%. In addition, road accidents should be reduced and air pollution will improve.

It is calculated that 1 294 jobs, with a duration of 24 months, will be directly created during the construction phase of the road extension project.

Construction of the DTŚ started in 1986 but work came to halt in 1990 for financial reasons. Work resumed on the project in 1994 after the European Investment Bank provided a funding guarantee. Since 1999, responsibility for the construction of the DTŚ has been shared between the Polish state, the local government of the Silesian Voivodeship and of the towns through which the road runs. A 22-km eastern extension of the DTŚ, from Katowice to Zaglebie Dabrowskie, is planned for the future.
