By 1838 the road had been completed to the northern frontiers of the Greole Desert, which was then the farthest Jamsterdavanian settlement south, across the Grolihari Desert, at a place named Sixen. Eventually the road was pushed through central the Reole Desert in the 1840's where construction ceased due to a lack of funds. The National Trans-Dununder Road opened the desert regions and interior of Dununder for settlement and commerce.
The opening of the road’s initial sections saw thousands of travelers heading north and south across the deserts to settle the rich lands that outlined that arid region
Small towns along the Road's path began to grow and prosper with the increase in population. Towns such as Sixen, Darion, Reolia, Stockton (Now call Fort MacDougan) and Masta evolved into commercial centers of business and industry. Darion was the headquarters for three major stagecoach lines, which carried passengers over the Road. Many small towns and villages along the road contained taverns, blacksmith shops, and livery stables.
By the early 1850's technology was changing the way people traveled. The makeshift road could not handle the traffic that was demanding passage.
Nathan Brigger, a wealthy Smalltree native, sought to enhance the road and make it more suitable for long trips.
Brigger began the construction of he improved road after securing the rights from the Jamsterdavanian Parliament. The final stretch of the road was completed in 1859.
The road saw increased activity until the 1890’s with the completion of the Deutsche and Great Western Railroad that paralleled the road. This spelled doom for the Brigger Road. As the traffic quickly declined, many businesses dependant of the traffic went out of business.
Just as technology caused Brigger Road to decline, it also led to its revival with the invention of the automobile in the early 20th century. As "motor touring" became a popular pastime the need for an improved Brigger Road began to grow. Many early wagon and coach roads such as the Brigger Road were revived into smoothly paved automobile roads. The Jamster National Highway Act of 1912 established a program of united Dununder powers to aid to encourage the construction of "an adequate and connected system of highways, interstate in character." By the mid teens the Brigger Route rose out of the ashes of the Brigger Road.
Due to the increased automobile traffic on Brigger Route a whole new network of businesses grew to aid the 20th century traveler.
Development of the road was further hampered during the Third and Fourth World Conflict, however the service station replaced the military post as the most common sight by 1956. Some of the Brigger Road era buildings regained new life as restaurants, tourist homes, antique shops and museums. Brigger Route served as a major North-South artery until the Dununder Highway Act of 1996 created the Inter-Dununder system, as we know it today. With the opening of the Inter-Dununder much traffic was diverted toward the old route.
Brigger Route is currently under the Jamster National Department of Transportation with it central officer located in Mission San Greo, Dununder.
