The snow plow routing problem is an application of the structure of Arc Routing Problems (ARPs) and Vehicle Routing Problems (VRPs) to snow removal that considers roads as edges of a graph. The problem is a simple routing problem when the arrival times are not specified. [ 1 ]
With the advent of rail travel and later, the automobile, a number of inventors set about to improve existing snow plows. In the US, the "snow-clearer" is said to have been patented as early as the 1840s, [8] for railways. The first snow plow ever built specifically for use with motor equipment was in 1913.
The wedge plow or Bucker plow was first developed by railroad companies to clear snow in the American West. The wedge plow forces snow to the sides of the tracks and therefore requires a large amount of force due to the compression of snow. The wedge plow is still in use today in combination with the high-maintenance rotary snowplow.
In 1929, NC 90 extended east from Columbia to Fort Landing. In 1932, US 64 was established and was overlapped on NC 90 from just west of Statesville to Fort Landing. In late 1934, NC 90 was removed from all overlap with US 64 east of Statesville; at same time, NC 90 was extended west from Lenoir to US 221 near Linville, replacing NC 171.
North Carolina Highway 268 Alternate (NC 268A) was established in 1940 as a renumbering of NC 268. This short 0.18-mile-long (0.29 km) route serves as a cutoff between NC 268 and NC 18; it is four-lanes throughout. Signage at the location only indicate it as part of NC 268; however, NCDOT county maps identify it specifically as NC 268A. [14]

The current designation of NC 91 first appeared on the 1948 North Carolina state transportation map, travelling from US 258 and NC 102 north of Snow Hill to US 264 north of Walstonburg. [18] By 1958, the highway was rerouted near its southern terminus to run directly to Snow Hill instead of using its previous alignment which ended north of the ...
