why is hammersmith bridge closed

Hammersmith Bridge is closed because engineers found structural cracks in its cast-iron pedestals, creating a serious safety risk. It first closed to motor traffic in April 2019, and it was later closed completely in August 2020 after hot weather worsened the damage.

Quick Scoop

The bridge is a historic suspension bridge, which makes repairs unusually complex and expensive. Recent reporting says it could still be years before full reopening, with one 2025 BBC report warning it may remain shut until 2035.

What happened

• 2019: Closed to motor vehicles after cracks were discovered in the bridge’s pedestals.

• 2020: Closed to pedestrians and cyclists too, after the heat made the cracks worse.

• Now: Only pedestrians and cyclists are permitted again according to recent reporting, while major repair funding and planning continue.

Why it’s taking so long

The main issue is not just the crack itself, but the age and design of the bridge. Because it is an old, listed suspension bridge with cast-iron components, fixing it safely needs specialist engineering and substantial funding.
