From Thursday, there'll be a number of changes for drivers at the intersection at Woodward Street and Wentworth Lane, most notably Wentworth Lane again being open to traffic.

The roundabout will be functioning normally for traffic, however it will not be complete, with some remaining parts of the project, including pedestrian refuges or median islands, garden beds, footpaths, spray grass, line marking, kerb and gutter sections and signage, expected to take an additional two weeks to complete.

Until that time the roundabout will remain under traffic control, so motorists are warned delays will be experienced. Traffic speeds through the roundabout will be kept at 40km/h during this work.

The power pole in the middle of the roundabout will also be moved, starting on June 18.

The project, worth about $840,000 was partly funded by the NSW government through the NSW Safer Roads program, with $695,000 with the remaining funding from the council.

In September 2017 City of Orange Traffic Committee chairman and councillor Russell Turner said the intersection had long been a "confusing" one.

"With the expected traffic in Wentworth Street when the southern distributor reaches that far, it would be an increased blackspot," Cr Turner said at the time.
