Section 6: Signing for Gravel Roads
Signing for Gravel Roads
Introduction
Due to the energy sector's impact on the state's highway network,
some highways are being converted to gravel.
Signing Guidelines
A REDUCED SPEED AHEAD (W3-5) should be installed in advance
of the change of pavement surface area and speed limit. PAVEMENT
ENDS (W8-3), NO CENTER LINE (W8-12), and a ROUGH ROAD (W8-8) or
LOOSE GRAVEL (W8-7) should also be installed in advance of the change
in pavement surface. Any or all three of these signs could include
a NEXT X MILES (W7-3aP) plaque. A SPEED LIMIT (R2-1) sign should
be installed at the point of the speed limit change as established
by a Transportation Commission Minute Order.
The NO CENTER LINE (W8-12), ROUGH ROAD (W8-8) or LOOSE GRAVEL
(W8-7) and SPEED LIMIT (R2-1) sign should be repeated every two
miles or after major intersections along the route. Engineering
judgement can be used to alter the spacing when necessary.
