Eric Carson, a Gloucester sawmiller and road builder, carved the first road through the ranges to bring out the magnificent hardwood from the forests on the Great Divide. After Carson spent many years trying to persuade local politicians that a road should be built across the Divide from Gloucester to Nowendoc, he went ahead and built it. Carving the route out of some of the steepest and most rugged countryside in the state was fraught with danger, but by 1961 it was complete. Carson's Lookout, which commemorates his work is between Gloucester and Nowendoc, is a stop off point for the enjoyment of panoramic views.
Route
At a total length of about , it is very hilly and winding as it passes across the Great Dividing Range. It is very popular with tourists, including motorcyclists, as it offers many pristine picnic and fishing spots. Riverside camping spots are available at Gloryvale Reserve and Bretti Reserve. There is also a picnic area, with toilets, near the Barrington River bridge. Occasionally a dingo, koala or wombat may be among the animals to be spotted on this route. Bellbirds are frequently heard shortly after beginning the ascent up the mountain. The only villages between Gloucester and Walcha are Barrington and Nowendoc, which is slightly north of this road. There is a public school and church at the hamlet of Rookhurst. After passing through Walcha, Dangar's Lagoon is situated close to Uralla where a statue of Captain Thunderbolt on horseback is located on the intersection of the New England Highway and Thunderbolts Way. After passing Uralla the Mount Yarrowyck Nature Reserve is near the junction of the Armidale Road and Thunderbolts Way. This site protects an Aboriginal cave painting site and much of the natural environment of Mount Yarrowyck. A new bridge constructed in 2015 crosses the Gwydir River shortly before reaching the KingstownRoad intersection and then the village of Bundarra. Once again the Gwydir River is crossed, this time by the Bundarra Bridge, a five-span iron lattice truss bridge, that was constructed in 1881. This bridge is long and wide between kerbs. It has been listed on the Register of the National Estate, being of state significance due to its design, historical value and aesthetic appearance. The next village encountered is Gilgai which is situated about south of Inverell.
