Parts of the road were diverted over the following years, including the Mold,[10] Ruthin[11] and Drws y Nant[12] sections, and it was truncated at the Dolgellau end when the town was bypassed.

The next stage of the scheme was to widen a 2.5-mile (4.0 km) stretch of the A494 from the River Dee up Aston Hill to the Ewloe Interchange, the junction of the A55 and A494, to three and four-lane plus hard shoulder standard.

In April 2006, local residents living at Aston Hill, part of the proposed route, began a campaign to oppose any further widening of the A494.

[14] After 15 months, protesters' high-profile message had garnered more than 2,300 individual letters and numerous petitions rejecting the proposals.

In March 2008 the proposals (in entirety) were ordered to be scrapped by Ieuan Wyn Jones, Deputy First Minister, responsible for Transport at the Welsh Assembly.

In reaching my decision I have taken account of the concerns raised by the inspector that the overall size of the scheme would have a significant impact on the landscape and would affect walking and cycling routes.

I have also noted [the planning inspector's] remarks that while he considers that this section of the A494 will need some form of improvement in the foreseeable future, he considers that the scale of the scheme as originally proposed is greater than required.——Deputy First Minister Ieuan Wyn Jones[16] This part of the A494 will remain a two-lane dual carriageway and the speed limit will be 50 mph (80 km/h).

The A494, which follows a largely unchanged historic route, passes Mold through the Clwydian Mountains, down to Ruthin and on to the market town of Corwen.

Likewise a dangerous road junction for Moel Famau, just outside Loggerheads, that was on a bend and blind brow has now been completely bypassed.

It then runs adjacent to Bala Lake (Welsh: Llyn Tegid) for 4 miles (6.4 km) and past Aran Fawddwy.
