The Environment Agency is getting ready to carry out essential maintenance on Lymington's Toll Bridge Road floodgate this November.

Residents in Lymington will benefit from improved flood protection following essential maintenance work at the town’s floodgate on Toll Bridge Road this November.
The Environment Agency will replace the floodgate’s sill plate, which has become loose over time. The new concrete construction will be more durable and better able to withstand heavy traffic, ensuring the floodgate continues to protect homes and businesses for years to come.
The team will also repair the valve system that controls tidal water flow, which was damaged during storms last year, and fix sunken road surfaces behind the floodgates.
Lymington is at risk of flooding when high river levels coincide with high tides, which can cause the river to overtop its banks.
The floodgate was installed in 2008 as part of the Lymington Flood Alleviation Scheme (FAS), a wider project to protect the town from flooding.
The gate is designed to operate during major flood events. Since installation, the gate has been closed several times as a precautionary measure but was last needed operationally during the severe winter floods of 2013/14.
Regular maintenance is essential to ensure the gate remains fully operational and ready to protect the community when required.
Work begins next week on Monday and is expected to finish by Saturday 15 November.
This is the first of two phases of improvement work. The second phase, which will involve replacing the tidal gate mechanisms, is planned for early 2026.
WaterBriefing is supporting the upcoming Floodex & National Drainage Show which takes place in London on 26 – 27 November 2025 in London. Now in its tenth year, Floodex will run alongside the National Civils Show, opening the event up to whole new audience of thousands of interested civil engineers, contractors, developers and planners, involved in construction, utilities, highways, railway and coastal defence professionals.
