The main road through Coddenham has been closed due to "severe flooding" as forecasters predict further rainfall.
Suffolk Highways has introduced the emergency closure along Lower Road and Spring Lane in Coddenham following the downpour.
A diversion route will be in place for the duration of the closure, which is yet to be confirmed.
The closure comes after flood alerts were issued across Suffolk and north Essex as forecasters predict rain to fall over the weekend.
The government has issued alerts for the Thorpeness Hundred, Deben, Lark, Gipping, Colne and upper Stour, with minor flooding possible on low-level roads.
