Drivers are being warned of a 30 minute diversion route while an emergency road closure is in place. 

Suffolk Highways is expected to close the B1115 Lavenham Road in Great Waldingfield from 8pm on Tuesday to 5am on Wednesday. 

According to the Suffolk County Council website the official diversion route is 20 miles long.

The diversion route is long because it includes A-roads as some larger vehicles are unable to fit down smaller routes that other drivers may use as shortcuts. 

The road will be closed from the roundabout at the White Horse to the Little Waldingfield turn-off.
