Economy and Infrastructure Secretary Ken Skates has selected the red route as the preferred choice to alleviate congestion problems in the Deeside Corridor, A55/A494/A548, area.
The scheme involves building increased capacity on the existing A548, with a new road linking the A55 and A548 just after the Flintshire Bridge.
The project is part of more than £650 million being invested by the Government in infrastructure improvements for North Wales.

The Economy Secretary said: "I'm delighted to announce the red route as my preferred option to address the congestion problem in the Deeside Corridor, A55/A494/A548, area.
"Having taken full account of the technical, social, economic and environmental aspects of the scheme and listened to the consultation responses, I'm confident that this significant investment will address the existing problems and compliment improvements across the Deeside area.
"The next steps will be to develop a preliminary design, which considers the environmental and engineering issues in more detail and looks to address some of the issues raised during the consultation."
Mr Skates also announced he would be progressing the delivery of the A494 River Dee Bridge Improvement scheme, which will investigate options to resolve the existing traffic bottleneck and overcome issues with the existing bridge.
