  Details regarding the 1904 reinforcement project: "...It was therefore decided to renew all the suspension rods, and pins, and to fix steel cables above the suspension links, to supplement them so that the maximum stress in the links due to any possible travelling load should not exceed 5 tons per square inch. It was also decided to build a stiffening girder coupled to the suspension rod on each side of the bridge, and at the same time to widen the bridge by building a footway 6ft. wide outside the suspenders on the north side of the bridge."

Notes:

• 1839 (or 1840): Restored. Deck strengthened.
• 1893: Original wood deck replaced with a steel deck.

• Became longest suspension bridge by eclipsing 1820 Union - Horncliffe, Berwick-upon-Tweed vicinity, England and Fishwick, Scotland, United Kingdom.

Notes:

• 1830: Said to have collapsed under weight of cattle in 1830. At some point it was rebuilt as a non-suspension bridge with the original suspension bridge towers intact. The current (in the 2020s and for many years before) main span is steel plate girder.

Notes:

• "Chine" is the spelling/pronounciation of "Chain" in Geordie a dialect spoken in Tyneside.
• Widened (19ft 6in roadway, two 6ft walkways), iron chains replaced with steel cables 1931. Bypassed, 1967. Since demolished.

  "A complete renovation of the road and foot bridge, currently covered in mould and rust, could take up to 40 weeks… The plans outline ‘refurbishment to the bridge, including works to the carriageway, footway, towers, lighting, drainage, parapet posts and timber rails’."

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.

February 22, 2021 Engineering News-Record article discusses proposal to thread a temporary truss between the towers to allow traffic while the larger suspension bridge repairs are completed. Recaps the issue: "Cracks have been found in the cast-iron pedestals that support suspension cable saddles at the abutments. Engineers suspect that roller bearings between the saddles and pedestals seized up at least 30 years ago…"
