There are no current plans to shut the Orwell Bridge when Storm Bella hits Suffolk - although Highways England says forecasted gusts are "on the cusp" of closure thresholds.
A Met Office yellow weather warning for wind comes into force from 3pm today until midday tomorrow and winds could reach 50mph - which is around the threshold for bridge closures.
The risk times are between 8pm tonight and 6am tomorrow, the agency said.
Storm Bella is expected to bring disruption across the UK, with severe gales and heavy rain forecast.
Winds of up to 70mph could hit exposed coastal locations in the UK.
