A stretch of the M5 was closed between Taunton and Bridgwater this afternoon amid fears that a horse would run on to the motorway.
The RSPCA was called to rescue the animal from a field by the motorway, and requested that the southbound carriageway between junction 24 and 25 was closed.
The request was made because of fears that the horse would become spooked during the rescue attempt, jump a fence and run into rush-hour traffic.
The motorway was closed for around ten minutes shortly before 5pm.
Although the rescue was successful and the carriageway was quickly reopened, the incident still caused major delays.
Traffic built up at both junction slip roads, and drivers were left facing delays of up to an hour due to the congestion.
It's been a busy day for M5 traffic disruptions, and drivers were also delayed this morning due to some hazardous conditions and lane closures.
Surface water was reported near junction 26 for Wellington, and rush-hour motorists were urged to reduce their speed and take care following some heavy rain overnight.
Meanwhile, one lane was closed on the southbound carriageway near Bridgwater, due to a broken down tanker and subsequent recovery work.
Drivers were being told to approach with care, near junction 24 at Bridgwater South.
There was also a 50mph speed limit in place northbound between junction 24 and junction 23 for Bridgwater North, due to a lorry strap on the carriageway.
