Changes will be made to Hewletts Rd, one of Tauranga's busiest roads, to boost public transport and ease traffic.
A new bus lane would be installed near the marina for buses travelling towards Mt Maunganui and the bus lanes near the port would be extended.
An extra right turn would also be added for vehicles exiting Jean Batten Dr to help traffic flow and reduce the time vehicles wait at the traffic lights.
Work on the changes would begin in June and were expected to be finished by August 2017.
The lane for a left turn into the marina would become a bus lane, meaning only buses, cyclists, motorcyclists or cars turning left would be able to use it.
