Notes:

• 2019, April: Closed to vehicular traffic due to safety concerns after an inspection found fractures in the cast iron casings around the bridge pedestals. Some repair work followed, but was not fully funded or finished (as of mid-2020)
• 2020, August: Fractures found to have worsened during recent heatwave. Bridge is completely closed to all pedestrian and bicycle traffic. Pedestrian walkways under the bridge and all river traffic under the bridge are also prohibited (implying risk of collapse).
• 2020, December: Bridge may reopen to pedestrians and cyclists if deemed safe by maintenance contractor, Mott MacDonald.
• 2021, January: Plan discussed to "thread" a temporary truss along the length of the deck to permit traffic while the suspension bridge undergoes repairs.
• 2021, March: Feasibility study on "double-decker" temporary truss plan determines it is feasible, possibly opening to pedestrian and vehicular traffic by mid-2022.
• 2021, July: Reopened for pedestrian and bicycle use.
• Replaced 1827 Hammersmith - London, England, United Kingdom.

Engineers suspect that roller bearings between the saddles and pedestals seized up at least 30 years ago…"
