National road B474n is newly built as bypass of the towns of Waltrop and Datteln. At section Datteln, construction started in October 2019. Within its 4-km-long course, the town bypass crosses the Dortmund-Ems Canal, requiring an overall ca. 204-m long bridge structure. This structure comprises the canal bridge and a foreland bridge.
Additionally included in the project are:
• preparation of bore levels, pre-assembly area (canal bridge)
• dam construction for a cyclists and pedestrian path of a length of 185 m
• preparatory works for construction of the section from km 8+918.54 to km 9+934.28 until upper edge of frost protection layer
• construction of an access ramp via the north road trough (Markfelder Strasse)
• construction of a ca. 250-m long dam, north foreland bridge
