The Messebrücke I is a 6.00 m wide concrete slab resting on steel supports. This structure was built without joints and spans 94.30 m. The slender concrete slab with a thickness of 0.30 m is curved in plan and deepens up to 0.70 m over the main spans of 9.00 m and 12.00 m depending on the stresses. Both ends of the steel supports are affixed to the main spans. The other supports have hinged connections at either end. The walls of the abutments (approximately 4.00 m high) and the base of the supports rest on a pile foundation.

Height: slab thickness at mid-span 0.30 m, height at the supports 0.70 m
