THE A419 Ebley bypass is closed in both directions due to flooding.
Heavy rain has caused problems for motorists in Stroud and surrounding areas throughout the day.
Drivers are urged to take care on the roads.
Gloucestershire Police Inspector for Roads Policing, Jason Keates said: "Don’t forget that braking distances can more than double on wet road surfaces.
“So keep your speed steady and slow and keep plenty of space between you and the car in front.
“I’d also suggest that in poor weather you allow extra time to complete your journey.
"Trying to reach a destination within a tight time-scale, especially in poor weather conditions, increases stress and the potential for a collision."
Drivers are also urged to prepare their vehicle and make sure it is in good condition before setting out on a journey.
Other tips suggested are:
* Use your brakes cautiously. Abrupt braking can cause brake lock-up and cause you to lose steering control.
* To make Antilock Brakes work correctly, apply constant, firm pressure to the pedal. During an emergency stop, push the brake pedal all the way to the floor, if necessary, even in wet conditions.
* Don’t make sudden changes in steering as this increases the potential for loss of control.
