A record of almost 30 crashes in the past five years at Masterton's Chapel and Renall St roundabout is behind the New Zealand Transport Agency upgrade.
In letters and texts sent to the Times-Age, readers questioned why there was a need for the intersection improvements which started this month.
The upgrade will improve the existing pedestrian crossing points, realign the traffic islands to slow vehicles entering the intersection and add new road markings to help guide traffic through the intersection.
There will also be new raised pavement tiles installed to make it easier for visually impaired pedestrians to use the crossing safely.
New Zealand Transport Agency regional operations manager Mark Owen said the new safety features were expected to slow down drivers.
