This week’s scheduled maintenance work on the Navajo Nation included grading along sections of the N212, N213, N6230, and N6730 roads.
Surface Enhancement Projects: By the Numbers
A trio of surface enhancement projects for BIA school bus routes on the Navajo Nation was completed in Fall 2023 by Public Works’ contractors.
These projects, which added much-needed road surfacing material to sections of N6720, N6732, and N6910, required almost 500 truckloads of materials from Public Works’ Sheep Hill facility to complete:
N6720: 2.5 miles of surface enhancement requiring approximately 3,700 cubic yards (yards3) of road surfacing material.
N6732: 2.9 miles of surface enhancement requiring approximately 2,600 yards3 of road surfacing material.
N6910 (north) 1.1 miles of surface enhancement requiring approximately 1,100 yards3 of road surfacing material.
In total, over 7,400 yards3 of high-quality road surfacing material were used to enhance over 6.5 miles of roadway on sections of these three school bus routes .
These surface enhancement projects were necessary because these school bus routes, like others in the area, have a high clay content that makes them very susceptible to moisture. This, in turn, creates muddy driving conditions and hinders travel during and after inclement weather.
