Road bridge over the Tersluis

In the Groningen – Meerstad district, the ‘Tersluis-Brug’ complements the new bridge family with a uniform, architecturally sophisticated design. The timber-concrete composite construction replaces an embankment that did not allow continuous boat traffic and creates free passage with a clearance profile of 1.5 x 4.0 metres.
Designed for road traffic of up to 30 tonnes, the bridge combines functionality with harmonious integration into the surroundings. The straight alignment enables a direct connection to existing roads. The block-glued timber girders vary in height: slimmer in the centre, they widen towards the abutments.
The supporting structure consists of three parallel glulam beams, which are coupled by a reinforced concrete carriageway slab and designed as an integral frame structure. The timber girders are rigidly anchored in the abutments, while the carriageway slab protrudes laterally to protect the girders from driving rain. Cerves in the timber girders secure the shear bond, while bolts stabilise against uplift forces.
The railing picks up on the design concept of the bridge family: a handrail made of acetylated glulam and a railing height of 1.30 m offer safety and aesthetics.
