This is like a motorway junction expanded and thus still testifies to the planned gap closure as a continuous highway to Wittlich.

The route leads four lanes immediately south of the Rhine past Ingelheim and Heidesheim am Rhein to the motorway junction Mainz, where the A 643 branches off to Wiesbaden.

From the Ingelheim-West interchange, the hard shoulder of the southern, from the junction Heidesheim also the hard shoulder of the northern directional lane in each case up to the triangle Mainz to a regular third lane is marked and instead, isolated emergency shelters have been built.

A full expansion to six lanes with hard shoulder also between Ingelheim-West and Cross Mainz-South is included in the urgent need - bottleneck elimination of the Federal Transport Infrastructure Plan 2030.

Immediately after that, the Mainspitz-Dreieck connects the A 671 to Wiesbaden and Mainz-Kastel, which forms the eastern part of the Mainzer Ring.
