Motorists travelling in both directions on the M55 were halted by police due to a "police incident" at around 6.30am this morning (October 7).
Highways officers and emergency services were at the scene - located between junctions 3 (Wesham Interchange) and 4 (Marton Interchange).
Severe delays and congestion followed the closure and motorists were asked to avoid the area.
A spokesman for Lancashire Police said: "We have had to close the M55 at Junction 3 (Kirkham) due to an ongoing incident.
"Please avoid this area for the time being to allow emergency services to deal with this."
A diversion was put in place to remove road users trapped on the motorway, but Highways England has now confirmed the M55 has reopened in both directions.
A spokesperson for Highways North West said: "The M55 has now been re-opened in both directions between J3 (Wesham) and J4 (Peel Hill) following the earlier police incident.
"Thanks for your patience and apologies for any inconvenience."
The nature of the incident has not yet been confirmed.
