Mainz / Wiesbaden (dpa) - A sensational action between Mainz and Wiesbaden is nearing its end: the last large section of the new Schiersteiner Bridge has arrived on a pontoon ship in the Mombach arm of the Rhine.
There it should be hoisted into its final position in the new structure of the Autobahn 643 on Thursday between the Rettbergsaue river island and Mainz-Mombach with a kind of giant pulley block.
The dimensions are enormous: The preassembled bridge section on the Hessian bank of the Rhine weighs 2,000 tons and is 120 meters long.
Work on the so-called floating in of the last of four large sections of the new Schiersteiner Bridge began on Monday.
The road builders had to wait for the Rhine to have a sufficiently high water level.
Around a dozen specialists were on duty.
The Schiersteiner Bridge is expected to be ready by the end of 2021.
At this junction in the Rhine-Main area, traffic has been rolling over the first new partial bridge over the Rhine since November 2017.
At the transition from the Rhineland-Palatinate bank to the new partial bridge, only 40 km / h is allowed on the four narrow lanes.
The second parallel partial bridge is still being built.

In future, the A643 should have six lanes here.
The total costs are estimated at 216 million euros.
The Schiersteiner Bridge was built in the 1960s for around 20,000 vehicles per day; in 2012, 90,000 vehicles rolled over it every day.
The old four-lane A643 bridge made headlines in 2015 with a construction accident and a total closure.
