8-Lane Upgrade of the A 99 Munich Motorway Ringmore
The A 99 is one of the busiest motorways in Germany – up to 160,000 vehicles use the eastern bypass near Munich every day and traffic jams are a daily occurrence. To improve the situation, an 8-lane upgrade of the motorway is being designed and has been under construction for several years. In March 2020, ILF Consulting Engineers was commissioned by the Autobahndirektion Südbayern to provide design services for the upgrade of the A 99 between the Kirchheim and Haar junctions.
The approx. 8 km long 8-lane upgrade of the A 99 and approx. 4 km long upgrade of the A 94 also include the conversion of the München-Ost motorway junction into a modified windmill with two semi-direct ramps. Additionally, the Feldkirchen-Ost, Parsdorf and Haar junctions are to be adapted. The complex conversion and upgrade is being carried out without interrupting traffic.
ILF Consulting Engineers is responsible for the following areas: road design, structural design of civil engineering structures (noise barriers and supporting structures) and project management, as well as various supplementary design services such as comprehensive construction phase and traffic management planning and coordinate transformations of basic data.
