Establishing priorities other than repaving The identification of new construction priorities uses much of the same information. However, safety factors such as accident rates, traffic volumes and capacity-building are usually given greater consideration. The majority of new construction is primarily 100-series highway work. In recent years, with limited government spending, TPW has focused on repaving and maintaining the existing paved network. Gravel roads are treated as part of the TPW's regular summer maintenance program.
Work includes graveling, ditching, grading, dust control, and surface treatments.
