Cars will have to give way to cyclists while a busy central Auckland road is modified for the flagship Grafton Gully bikeway project.

The site is near where novice cyclist John Tangiia was killed in a collision with a truck two weeks ago while turning left from Parnell Rise into Stanley St.

The Transport Agency hopes to reopen a busy link to the Northwestern Motorway in central Auckland early next month, rather than keeping it closed until mid-March, as previously indicated.

Alten Rd between the motorway and lower Symonds St has been closed while traffic lights are installed to allow cyclists and pedestrians to cross safety between two sections of an $11 million bikeway the agency is building through Grafton Gully.


A second lane is also being installed for traffic turning right from the bottom of Alten Rd to the motorway.

It intends to install a new signalised crossing for cyclists and pedestrians making their way between two completed sections of the 1.9km bikeway, which will ultimately run from Upper Queen St to Beach Rd.

The agency is also adding an extra right-turning lane at the bottom of Alten Rd, giving vehicles easier access to the Northwestern Motorway via Stanley St.

Agency highways manager Tommy Parker said the temporary road closure would allow his team "to get in and do the work as quickly and safely as possible so that everyone can benefit early".

Although the Transport Agency's original target for completing the cycling "super highway" was December, Mr Parker said contractors were racing to open the off-road facility in September, when it will pass below Grafton Bridge and include a tunnel under Wellesley St East.

The route is an extension of the Northwestern Cycleway from Henderson.
