Historic Arch hewn through rock mountain

Just had a delightful day trip through the countryside along the Guy Fawkes & Boyd River for a picnic. Came across this historic hand hewn rock tunnel cut through the side of the mountain. This Arch was commenced in 1866 by a road gang and is still in use today. There is no way around this section of the road with out using this tunnel. Don't try it in a caravan though as the height is only 3.27m. We saw the old gold mining town of Dalmorton which used be home to 5 hotels, shops, blacksmiths, school, town hall, courthouse, police station/lockup butcher shop and a thriving rural community. That's all gone now except for some ruins and a dusty road along a beautiful river. It was 37 degrees Celsius and forecast to getting much hotter over the next few days. We saw a lone camper & 2 men on horseback during the whole trip. It would be a magnificent place to camp , fish & relax. Just make sure take all your supplies with you as there is no way to spend money on anything in this peaceful rural setting.
