Work to replace the roundabout at the busy Riccarton Rd/Deans Ave intersection with traffic lights gets under way today.
Fulton Hogan are doing the work which also involves renewing the underground water pipes and resealing Riccarton Rd through to Harakeke St.
One lane in each direction on Riccarton Rd will be kept open throughout the work, which is part of a comprehensive project to give buses priority along the busy thoroughfare.
More than 800 buses travel along Riccarton Road every day, but currently jostle with other traffic meaning it can take anywhere from three to 30 minutes to travel from Christchurch Hospital to Westfield Riccarton.
The Riccarton Road bus priority work will eventually stretch from Deans Avenue to Matipo St. The next phase of work will move west from Deans Ave to Harakeke St, building on the Riccarton Rd bus lounge and bus lanes from Division St to Matipo St completed last year.
It is expected all enhancements along Riccarton Rd will be completed by the end of 2017.
