The Millennium Bridge over the River Hull will be upgraded with a new computer control system next week.
The pedestrian swing bridge, which links The Deep to the Fruit Market, is currently controlled using the public switched telephone network (PSTN), which will soon become obsolete.
The Victorian-era copper phone lines, which deliver analogue landline services, are due to be switched off by the end of 2025, with all landline services in the UK to be offered digitally.
This means the Millennium Bridge needs a new computer-based control system to future-proof it for years to come.
The installation of the new system will take place from 9am on Monday 27 June until 8pm on Friday July 1, during which time it will not be possible to operate the bridge.
To allow the passage of river traffic, the footbridge will be kept in the open position during the work, meaning pedestrians will not be able to cross it. There will be a short diversion via Scale Lane Bridge.
Andy Burton, Hull City Council’s Assistant Director (Streetscene), said: “The national switch-off of the old copper phone network is coming, so it is essential that we are ready for it.
“The Millennium Bridge is being upgraded to a modern control system, which will ensure it continues to be available for use after the old network becomes obsolete.
“We understand this may cause some short-term inconvenience and we thank people in advance for their patience while this work is being being carried out.”
