Haringvlietbrug Steel Fatigue Reinforcements on A29, Netherlands

Rijkswaterstaat reports that contractor Hollandia Services is carrying out urgent steel reinforcement work on the Haringvlietbrug on the A29 route due to steel fatigue. Approximately 1,000 weld connections on the fixed bridge sections are being reinforced with bolted steel plates called overkluizingen. The work spans both the 80-metre and 1,060-metre fixed sections simultaneously, using mobile work platforms and hanging scaffolds to accelerate progress and ensure timely completion.

New Edition Bereikbaar Zeeland Magazine Published

Rijkswaterstaat has published the April 2026 edition of its digital magazine Bereikbaar Zeeland, covering infrastructure renewal projects across Zeeland province. The edition details maintenance work at five major facilities: Vlaketunnel (10-day major maintenance), Slaakbrug (nature-conscious repairs), Grevelingensluis (inspection-led maintenance), Kreekraksluizen (rapid fault response and phased maintenance), and Krammersluizen (seasonally-planned repairs ahead of major renovation). The agency notes that many structures date from the 1950s–60s and face constraints from budget limitations alongside increasing traffic loads and climate pressures.

Rijkswaterstaat Tests Fully Biobased Traffic Signs on A58 at Oirschot

Rijkswaterstaat has launched a 12-month field test of 24 fully biobased traffic signs along the A58 near Oirschot, in partnership with Plantics under the InnovA58 Living Lab programme. The signs are manufactured from Dutch hemp fibre combined with biological resin derived from sugar-industry and vegetable-oil production by-products, making them fully circular. Testing began on 15 April 2026 and will evaluate whether the biobased signs are technically equivalent to standard aluminium signs for use in all weather conditions. If successful, the findings could support wider deployment of circular traffic-sign infrastructure across Dutch and European road networks.
