Preliminary works on the $120m Bayfair to Baypark project will continue mostly at night next week, with traffic delays expected from Sunday evening.
Contractors are scheduled to remove large trees opposite 759 Maunganui Road which are currently in the way of the new northbound on-ramp.
The works will be completed by trimming the large trees to a manageable size, then felling them away from State Highway 2.
All traffic will be reduced to one lane along this section and pushed as far as possible away from the works.
This coming week the existing plastic barriers will also be replaced with steel barriers along the northbound shoulder.
The new barriers will reduce the deflection zone behind the barriers and increase the work area without affecting road users. Traffic delays are expected due to temporary speed limits and lane closures during work periods.
Sunday will also see the start of night works for a large drainage pipe to cross State Highway 2 north of the Bayfair roundabout. Works will happen at night under lane closures and a contraflow, and are scheduled to last until Friday, January 26.
The overall project involves construction of two flyovers, with one carrying SH29A over the railway line at the Te Maunga intersection. The second will take State Highway 2 traffic up and over the Maunganui-Girven Road intersection.
As part of the project, the existing Maunganui-Girven Road intersection will also be upgraded, the Te Maunga roundabout replaced with an elevated interchange, the Truman Lane roundabout improved, and safer walking and cycling connections provided between Baypark and Bayfair.
