Roads around the Lincolnshire Showground will be extremely busy for the next 48 hours as around 60,000 people head to and from the annual county show.
Traffic maps were painted red on the morning of Wednesday, June 20 on the A15 north of Lincoln.
The A15 from the A46 Lincoln bypass to the A631 at Caenby Corner is closed to all but show traffic.
Organisers of the Lincolnshire Show have asked that people follow advice given by Traffic Marshalls, Police Officers and Society Stewards.
Routes to the show will be signposted.
Stagecoach is also running a shuttle service between the showground and Lincoln City Bus Station and a regular bus service will be running every 15 minutes in both directions. It will leave the Lincoln City bus station at 8:30am.
