The train that ran from Chickamauga, Ga., to Durham on Lookout Mountain continued its slow ascent of the mountain after passing Nickajack Road near the lower slopes.
As the route approached the top, the convicts charged with constructing the route faced considerable obstacles. It was necessary to first build a long, sweeping trestle just below Eagle Cliff. Then there was a tall section of rock that must be gnawed through.
Another trestle was necessary along the steep bluff at the gorge below the thundering Lula Falls.
The route was hammered through a series of giant boulders and then dug out along the side of the falls and then on to Lula Lake.
A bridge had to be constructed across Rock Creek just above the lake.
Now a train bed had been completed through a section of some of the most scenic and awe-inspiring terrain in the Chattanooga region.
There were some lesser cuts necessary as the line continued just above Rock Creek. The route veered away from the creek at one point, then later rejoined it.
Another tall trestle (#11 of the 14 trestles along the rail bed) gapped a high gorge as the community of Hinkle was reached.
The route reached the present Middle Road.
The next section went along the present Higdon Lane to the current Hinkle Road (Highway 157).
