The Elztalbrücke is a motorway bridge on the A 48 over the Elzbach near Kaifenheim (Kaifenheim and Kehrig districts ) in the Mayen-Koblenz district . The girder bridge was built from 1964 to 1967 based on designs by Ulrich Finsterwalder and Herbert Schambeck . The bridge has a length of around 380 m and a maximum height of 97 meters above ground.

The prestressed concrete structure has eleven fields with spans of 20.9 + 9 × 37.5 + 20.9 m. The bridge superstructure is monolithically connected at both ends with the 20.7 m long abutment box and with all supports, but is divided by an expansion joint over the middle of the valley. The construction was called a multi-stemmed frame with immovable nodes . The bridge superstructure is supported by individual piers arranged in the middle of the bridge's longitudinal axis. The octagonal pillars have reinforced concrete hollow cross- sections with external dimensions 4.8 m × 5.8 m and are monolithically connected to the mushroom-shaped superstructure. The 30 m wide in-situ concrete slab has a variable thickness, a maximum of 2.45 m in the middle on the pillar and at least 45 cm on the edge. The superstructure was erected with a telescopic arm .
