Traffic is set to flow more quickly at a busy intersection in Christchurch now work on a new set of traffic lights has been completed.
The Transport Agency says work on the Marshlands Road intersection with State Highway 74 began in December.
The intersection is on the main route to the Port of Lyttelton and the main road to the city's eastern suburbs.
State highway manager Colin Knaggs says the road to Lyttelton is essential for much of the freight needed to grow the Canterbury economy.
Mr Knaggs says the $3.5 million project has been a challenge as the route has been carrying a lot more traffic since the earthquake in February last year.
The new lights were to be turned on at 9am on Saturday.
