Whanganui's mayor says a number of factors have led to traffic issues with the city's Dublin St Bridge.
Hamish McDouall said this week Whanganui needed a replacement for the congested 107-year-old bridge and the council was beginning the process of putting budget in the long term plan for the next three years.
"It's an old bridge, it's a narrow bridge and it also services a good connection between State Highway 3 and 4."
