The 3rd construction phase begins north of the Dortmund-Ems Canal and ends sharpening in the B235 at section 32, station 2+679. 2 bridge structures will be built for this purpose, one structure will be built in the course of the B474 via the Dattelner Mühlenbach at about km 10+251 and a bridge structure in the course of the laying of the Natroper way at about 10+341 via the B471 4.

The new node node of the B235 in the direction of dates is perpendicular to the B474 at the intersection and is therefore subordinated to the B474. The intersection is light-signal-driven and has separate left or right turn lanes. A special access road is planned at the intersection for the management of the adjacent agricultural land. There are no other direct access to the B474.

The section of the B235 is equipped with a one-sided walkway and bicycle path, as well as a safety separating strip. A traverse point is also set up in the connection area of the B235 towards dates. In the direction of Olfen, a bus stop on the street “zum Ringofen” is added to the east. The crossing point and bus bay receive tactile elements.

The drainage of the line is ensured via road troughs. Due to the sloped situation, these are partially separated by crossbars. As far as possible, the troughs are produced with a zero gradient to ensure optimum infiltration. In the transition from the 1st to the 3rd construction phase, the section directly behind the bridge over the Dortmund-Ems Canal, cascade recesses are planned on both sides for retention, evaporation and infiltration. These end into the road hollows in the 3rd construction phase.

Compensation measures are carried out next to the B474 until the Natroper Weg, including bat protection fences, as well as various afforestations.
