Ramsey swing bridge will not reopen in time for the Festival of Motorcycling due to the continuing repair work.
The bridge will remain closed until the end of August and work will continue through September, according to the Department of Infrastructure.
It will reopen to vehicles during the day from the end of August, but finishing works will continue during the evenings between Monday and Thursday for several weeks afterwards.
The Ramsey landmark was originally closed for maintenence in September 2013 and was estimated to reopen before Christmas, but engineers discovered unexpected problems when inspecting the mechanism.
The bridge is swung by a series of 20 iron wheels on a circular track that form a large bearing. It was revealed that they had been replaced by wheels that were an inch too small during the 1980s, causing repeated failures and deterioration of the mechanism.
Director of ports Ann Reynolds said: ‘The tuning and testing work over the last month has been essential to ensure that the mechanisms work effectively, and that the bridge is running smoothly and correctly to give maximum life and minimum maintenance in the future.’
She continued: ‘The refurbished Ramsey swing bridge - painted and with new lighting - will be substantially complete, as scheduled, by the end of August.
‘Then the bridge will be brought back into normal daily use so that Ramsey residents can use the bridge during the day. However, during September, weather and tides permitting, we will look to do finishing works on Monday to Thursday evenings after normal office hours.’
