BOSSES at Europe's largest surviving First World War aerodrome fear the site could close permanently after the road to its site has been shut for roadworks for 100 days.

Stow Maries, off of Hackman's Lane between Maldon and Chelmsford, claims the diversion is unclear and they have seen visitors numbers plummet. 

In April Essex and Suffolk Water began significant water mains work on Hackman's Lane, which were meant to last ten days.

However, the road remains closed more than 100 days on with work still not complete.

Ian Flint, Charity CEO, said: "We had no notice of the works – in fact, we only found out they were happening when we were passed a note from a neighbour. 

"With the drop in visitor numbers caused by these works, the survival of the museum is now really in question.

"We are in real difficulties – the works have been badly communicated from day one and as a business start-up, it's an uphill struggle as it is.

Mr Flint said attempts by museum staff to engage with Essex and Suffolk Water and Essex Highways had not proved successful. 

"The conversations we have initiated have given us no encouragement that things will improve," he added. 

"The only thing that can save the museum and secure this priceless facility for the community and nation is for the people of East Anglia to fight through the diversion and get to us. We need them to visit."

A spokesman for Essex Highways said the works would be paused next week so a "more suitable" traffic plan. 

They said: “We have been in talks with Essex and Suffolk Water (ESW) about the situation at Hackman’s Lane and are pleased they have agreed there should be an updated approach to traffic management to carry out the much-needed repair works.

“ESW has advised Essex Highways it will temporarily halt works on Hackman’s Lane by Saturday 13 July until later this year. This will enable ESW to develop a more suitable traffic management plan which allows residents, businesses and aerodrome visitors to continue to use the road.

“Essex Highways has been assured by ESW that residents and businesses, including the aerodrome, will continue to be updated with further information.”

A spokesman for Essex & Suffolk Water said: “We are sorry to hear the concerns being described at Stow Marie's Great War Aerodrome and the impact that has been outlined by other businesses.

“We have been in communication with Mr Flint in advance of, and throughout these works, and have been taking on board his concerns and those of other business owners.

“As a result, earlier this week, we drew up a plan to reduce the scope of the project, allowing us to finish work and leave the site by July 13.

"This was agreed by Essex County Council’s Highways team at a meeting yesterday (Thursday) and we have updated Mr Flint and reiterated the procedures we have in place for him to claim loss of income.

“It is important to note that we have worked hard to ensure access to the aerodrome has been maintained throughout the work.

“While this change of plans does leave a section of water pipes to be renewed in the future, we will work closely with Mr Flint and the other businesses in the area."
