From 21 March 2005, the bridge was temporarily restricted to southbound traffic whilst repainting and repair work was carried out on the 96-year-old structure, which was due to take almost a year to complete. It reopened for both lanes of traffic on 12 October 2006, having been partly closed for 18 months and costing £6.3m in repairs. Previously classified as part of the A1231, the road across the bridge was reclassified as the B1539 when the Northern Spire Bridge was opened to traffic on 29 August 2018.
