Bridge heights

Somerleyton Swing Bridge

Yachts need to lower their masts to get under many bridges in the Broads.

The exceptions are Reedham, Somerleyton and Trowse swing bridges, the lifting bridges on Breydon Water, Novi Sad and St Julian's pedestrian bridges in Norwich and the bridge at Carrow Road, Norwich.

Novi Sad Bridge, NorwichArranging a bridge opening for the three Norwich bridges can be done through Broads Control on 01603 756056. At least 24 hours notice should be given.

Very limited times for Trowse rail bridge to open can be found in Notices to Mariners. These times are likely to change every six months.

Clearance measurements for bridges given are at Average High Water during summer. There will be greater clearance near Low Water, especially at Great Yarmouth and in the southern rivers. Barometric pressure, rainfall and wind conditions affect river levels so caution should be exercised and bridge gauge board carefully noted.
