The Environment Agency reported on 7 October 2026 that it had completed a two-year project replacing tidal outfall flaps and improving flood defences at Toll Road in Lymington, ahead of the winter flood season. The original steel flaps, installed around 18 years ago under the Lymington Flood Alleviation Scheme, had reached the end of their design life and were heavily corroded in places. New flaps of high-density polyethylene and marine-grade stainless steel were installed in September 2026 at low tide using divers and a crane.

The agency also repainted the flood gate, replaced worn seals, improved pedestrian access when the gate is closed and installed a quieter road surface. During the work, the team found leaking floats had affected the regulating valve that manages marsh water levels. Replacement floats have been ordered and will be fitted when conditions allow; meanwhile the valve has been temporarily closed as a precaution, which may lower marsh water levels. The agency said the valve would be repaired by the end of the year. Project manager Artur Podsiadly said the main project had been delivered as planned before winter. The scheme protects over 140 properties.
