CONWY County Borough Council have announced major refurbishment work to the flyover link from Llandudno Junction to Conwy.
The work to replace the waterproofing, movement joints and drainage on the bridge will be done in two phases, with the first phase starting on May 9, planned to last for 11 weeks.
The road will be closed to vehicles during the work, with a diversion via the A55 and Conwy tunnel.
The Weekly News roundabout is also affected - traffic will still be able to access Deganwy, Llandudno Junction and the Tesco roundabout, but not from all directions.
Pedestrians and cyclists will still be able to access the bridge via the steps near Lidl at the Llandudno Junction end of the site.
A Council spokesperson said: “We understand that this work will cause major disruption and inconvenience for residents, because the bridge is a main route into Conwy.
“But it’s because this is a key route that the work is so important, to keep the bridge safe and open for years to come.
“Dry weather is needed to complete the work, which is why it’s scheduled for spring and summer.
“We’re avoiding the main school holidays by starting after Easter and completing the first phase before the summer holidays.
“The second phase will be scheduled at a similar time next year.”
The bridge was last closed for major work in 1995.
