Recent road works removed the need to narrow the road from 2 lanes as the motorway exits merge, down to 1 lane for the approach to the lights at Lake Rd. There's now two lanes for the entire approach westbound along Onewa Rd. However, there's still a sign on the left at approximately 6 Onewa Rd (just prior) which suggests 2 lanes merge to 1. This confuses motorists who move to change lanes, get around the corner and realise they don't need to.
The sign needs to be removed as it's now redundant and it appears it was overlooked during the roadworks.
