Heavy rainfall over the past 48 hours is beginning to take its toll on the roads and the environment in parts of Wiltshire.

The Environment Agency has issued four flood warnings, which urge residents to 'act now', for areas across the county.

They cover the stretches of the Bristol Avon (upper) from Malmesbury to Chippenham and from Chippenham to Melksham, as well as the Upper Avon from Upavon to Amesbury, which covers Pewsey.

The fourth covers the River Bourne at Tidworth and Shipton Bellinger Village Centres.

The B3105 at Staverton causeway and the B3106 cut through to Holt have both been closed because of flooding and drivers are being advised to avoid the area.

In addition, a retaining wall at the junction of Masons Lane and Newtown in Bradford on Avon has collapsed and is currently being cleared.

Bradford on Avon Town Council says it has informed Wiltshire Council's highways department and has advised drivers to avoid the area.

Meanwhile, two trees fell and partially blocked the road from Bradford on Avon to Turleigh and the main railway line from Bradford on Avon to Bath.

The road has since been cleared and train drivers using the railway line were told to restrict their speed to just 10mph going past the area.

Wiltshire Council tree officers have been asked to assess a row of trees that are in danger of falling onto the main railway line from Bradford on Avon to Bath.

The damage occurred after more than half a month's worth of rainfall fell in just 24 hours.
