Drivers have been warned they could face disruption during weeks of work on a Thorpe St Andrew street - the latest work to protect homes from flooding.
Work to improve surface water drainage in Thunder Lane is due to begin on Monday.
The work will be happening from the junction with the ring road heading north to outside house number 130 in Thunder Lane.
Carrier pipes are being laid in trenches to discharge into a new drainage system on the ring road.
A spokesman for Norfolk County Council said: 'To maintain a safe working environment and to protect the workforce and members of the public, it will be necessary to limit access to vehicular traffic near to the work area.'
It is anticipated the work on Thunder Lane will take approximately 18 working days.
The spokesman added: 'Norfolk County Council recognises that this work may cause some disruption and access may be restricted at times.
'We apologise for any inconvenience this may cause. Further information will be provided to local residents when the works are taking place nearby.'
The work is being funded through Department for Transport Challenge funding. In April 2015. Norfolk County Council was successful in its bid for £9.1m of funding through that scheme.
The council added £1.2m to that and has been working to improve drainage in areas such as Thorpe St Andrew, Taverham, Drayton and Sprowston.
