The $13 million project involving the new roundabout and airport accessway began in May last year and is part of a $25m package of road improvements announced by the Government as part of the Matariki-Hawke's Bay Economic Development plan launched in July 2016.
The Watchman Rd project and new airport accessway was jointly funded from the National Land Transport Fund, Hawke's Bay Airport and the Napier City Council.
The old intersection, which had been the scene of a string of serious crashes, was tagged by the New Zealand Transport Agency as one of the region's most notorious safety blackspots.
At the other main roundabout project, the Pakowhai/Links site on the expressway, the roadway is now operating in its final configuration but at this stage only as one lane.
Temporary speed limits of 50km/h are in place through the work area and motorists are asked to be patient and drive with care on the approaches.
Meanwhile, slip clearance work continues on SH2 north of Napier between Tangoio and Raupunga.
Also on SH2 north seal-widening work is being done at various sites between Waihua and Tutira with lane closures and stop-go signalling in place at times.
Traffic control and speed restrictions are in place just north of Tutira where contractors are working on a drop-out which has reduced the roadway to one lane and motorists can expect some delays.
Drop-out repair work is also being done in Glencoe Gorge on SH50 with speed limits imposed because the highway is down to one lane.
On SH38 from Frasertown to Waikaremoana the stretch is open only for residents from Tuai on as the major clean-up continues.
