Work is continuing across the stadium at St James Park, the home of Exeter City Football Club.
The Old Grandstand, which dates back to 1926, is being demolished to be replaced by a new stand, and maintenance and safety checks continue to take place on the two existing stands.

A spokesman for the club said: "As part of our ongoing maintenance we have been working with Rope Access Engineers to test the bolts on the stands during recent months.
"There was particularly bad weather during the recent Port Vale game, and following reports by spectators of a loud noise from the roof of the Big Bank, the Rope Access Engineers have returned and checked as part of these works and are satisfied that the roof is structurally sound."
They added: "This is part of a continued programme of work at the stadium alongside the exciting redevelopment, and one of a number of areas that the club continues to work on."
