Wyrzysk Bypass is located on National Road No. 10. The project involved the construction of a single carriageway road with engineering structures. The work began in July 2008 and ended in early 2010. As a member of the consortium, Mosty Łódź constructed most of the engineering structures located on the bypass.

The work included the construction of:

• four four-span viaducts
• a single-span viaduct
• an over 240-metre-long bridge over the Łobżonka River valley

Project challenge: An obstacle to constructing the bridge over the Łobżonka River was mainly a deep glacial valley (the difference in height is approx. 25 m in relation to the surrounding area). The area is also a part of Protected Landscape Area "Łobżonka Valley and Kujańske Forests".
