A half-century old grandstand at Market Rasen Racecourse is being demolished due to serious structural issues - and will make way for a bigger bar.
The Family Enclosure grandstand, built in the early 1960s, was once extremely popular but has been in decline over the past few years.
The racecourse wants to get rid of the problem-hit family grandstand so it can double the size of its Tote Exacta bar and increase the capacity of the popular, more expensive, Tattersalls Enclosure.
Racecourse manager Pip Kirkby said: “This is an exciting development for Market Rasen Racecourse as we stage increasingly popular major racing days.
“It illustrates the confidence that The Jockey Club has in Lincolnshire’s only racecourse that this investment is being made.
“This is a good day for sport and entertainment in the county.”
But the £800,000 Jockey Club investment will leave little shelter for people in the cheaper family enclosure.
If plans are approved by West Lindsey District Council, work will start in the summer and be complete by the end of November.
Mrs Kirkby said the Tattersalls Enclosure was the most popular - and its size needed to be increased after three sell-outs in 2013.
She said: “Subject to planning approval from the local authority, we will get the work under way as soon as we can.
“The aim is to have everything completed in good time before our popular Boxing Day meeting.”
