A3 BW48 Danube Bridge Sinzing - Planning service for the replacement of the new building

The A 3 is one of the most important German motorways and, with a length of almost 780 km, the second longest motorway

Germany. It links the Rhine-Main region with Austria and Southeastern Europe. In addition, the A 3 is a

important lifeline of Regensburg: trade and commerce, industrial companies, educational and

Health facilities are located on both sides of the highway.

The A3 Nuremberg-Passau motorway is already heavily loaded. Especially in the catchment area of the regional center

Regensburg's long-distance traffic overlaps with urban traffic and heavy urban-suburban traffic.

Since 1990, traffic on the section to be planned has almost doubled. Due to the

The dynamic development of the regional centre of Regensburg is due to the superimposition of long-distance and

Regional traffic is already experiencing capacity-related obstructions to road traffic during peak hours.

The client (AG), Die Autobahn GmbH des Bundes, Niederlassung Südbayern, Außenstelle Regensburg

is planning the "6-lane expansion of the A 3 Nuremberg - Passau between west of the Nittendorf junction and the Regensburg junction".

In the course of this, it is intended to renew the affected structure as well. The aim of the overall project is to extend the A3

for the foreseeable transport needs.

The Danube bridge Sinzing (BW 48) is part of the planning scope of the 6-lane expansion of the A 3 Nuremberg - Passau in the

Section west of the junction (AS) Nittendorf and the motorway junction (AK) Regensburg. The

The planned expansion runs over a length of 12.75 km from Str.-km 478+500 to Str.-km 491+250. Since the

The Danube bridge over Sinzing is in poor structural condition, it is to be rebuilt in the course of the A3 expansion in the

early construction phase AS Sinzing - AK Regensburg.

The structural feasibility of the measure while maintaining traffic is particularly important in the planning phase

to be taken into account. The corresponding planning for traffic routing during construction will be carried out by the

Overall project "6-lane expansion AS Nittendorf - AK Regensburg" completed. For this purpose, correspondingly close

An important part of the planning is the dismantling of the existing bridge. Here, above all, the interests of DB must be taken into account.
