The M606 in Bradford is closed in both directions between the exit and entry slip roads at junction 3 due to flooding.
A diversion is taking drivers off and then back on the motorway at the junction. The road is likely to remain closed during the evening rush hour.
Highways England contractors are currently on-site and are working to clear the flood water from the carriageway as quickly as possible.
Drivers using this section of the M606 are advised to plan their journeys and allow some extra time to reach their destinations.
