A pedestrian has died three weeks after being struck by a cyclist on a residential street.

The 66-year-old woman was trying to cross Dandelion Dr in Rowville — in Melbourne’s southeast — when she was hit by a cyclist about 1.35pm on June 26.

Paramedics treated the woman for serious injuries before taking her to hospital.

The cyclist, a 49-year-old man, was treated for a minor injury.

An investigation into the incident is ongoing, and no charges have been laid.
