9.3.2 Primary Roadways

primary roadways

Primary roadways are arterial routes that connect major activity centers; provide the primary access through the installation; and offer the means by which most people view the installation.  These roads are shown in yellow on the visual analysis maps in Section 5.  These roadways often traverse the entire installation and carry the heaviest volume of traffic that results in high-speed and high-visibility corridors.  Direct access to this type of road should be restricted to crossing at major intersections.  Primary roadways are designated as boulevards in urban areas and as avenues in rural and suburban areas. Design characteristics include:

• Continuous, through-traffic alignments that are relatively straight or large-radii curvilinear to handle moderate to heavy traffic.

• Alignments that form the boundary between different land uses are preferable to alignments that transect a land use zone.

• Two or more moving lanes in each direction typically divided by a median.

• Controlled access and a minimum of curb cuts limited to entranceways to major facilities or building groups.

• At-grade intersections with signal controls.

• On-street parking prohibited. 

• Medians, street lighting, signing, and planting that enforces the moderate-to-high speed nature and importance of the road.

• No grade greater than 10%.

Curbs, gutters, and sidewalks provided in all cantonment areas and other residential areas with densities greater than two dwelling units per acre.
