| Abstract: |
The Chemnitz viaduct, which was built between 1901 and 1909 for a four-track operation, was tech- nically refurbished and reinforced for modern use in accordance with the requirements of the his- torical monument preservation. The two inner tracks will be used for future railway traffic, while the outer bridge structures will accommodate inspection, maintenance and emergency routes as well as technical equipment. The approx. 275 m long and 17.50 m wide bridge consists of 2 arch and 10 girder segments. During the technical repair, the inner girder segments were renewed as a steel- concrete composite structure. The other structures were repaired, strengthened and supplemented with a reinforced concrete structure above the curved steel sheet. This article begins with an over- view of the existing bridge structure and its future use. This is followed by explanations of the plan- ning and execution of the construction work. |
