AFTER two fatal car crashes and several collisions, a section of Kyogle Rd at Uki will have its speed limit dropped by 20kmh in a bid to save lives.

A review by the Roads and Maritime Services has found the existing 80kmh speed limit on Kyogle Rd, 300m south of Braeside Dr to 250m south of Glenock Rd, will be reduced to 60kmh.

In February, a 67-year-old man died after losing control of his vehicle on the wet road. It flipped upside down as it plummeted into the nearby creek, leaving him submerged in the vehicle.

On the same stretch of road in January 2015, a woman died and six people were injured, including a 15-year-old girl who was left in a critical condition, after the cars they were in collided head-on.

Tweed Shire Council's manager of roads and stormwater Danny Rose said new road traffic signs would be installed along the road with further remedial works in the pipeline to address the carnage.

"This section of Kyogle Road has been the site of several crashes over recent years, including two fatal crashes," Mr Rose said.

"The purpose of the speed zone change is to slow motorists through this section of road while the results of recent road safety audits can be considered.

"Remedial works can be designed and costed, and applications for black spot funding prepared and assessed by the relevant agencies."

The speed limit change will not come into effect until new signs are installed on July 28.
