There will be no public car-parking beside Royal Portrush, with park and ride facilities operating instead.
Charges will apply at the park and ride, with a fee of £17 during the four championship days Thursday to Sunday (17-20 July).
Organisers have urged fans to use public transport, but an industrial dispute at Translink could lead to trains not running on two days during The Open.
The Transport Salaried Staffs’ Association (TSSA) has earmarked Friday 18 and Saturday 19 July for strike action involving some of its members.
If the industrial action goes ahead, it would involve widespread disruption to rail services on those days, not just in Portrush.
Translink say they are doing everything they can to avert the strike.
Extra bus and train services to Portrush are planned from 14 July, with fans urged to arrive 30 minutes before departure time as services are likely to be busy.
Sarah Simpson, Translink’s northern area manager, said: “There will be enhanced train capacity and frequency, including additional services to Portrush and late evening return services.
“Special bus and coach services are also available in addition to normal Goldliner services.
“I would encourage anyone heading to The Open to visit our website for travel options, external.”
