Revision as of 02:03, 5 June 2016

Overview

The goal of this page update is to clarify handling of the dirt road type in Illinois by revising the Special roads section of the Illinois wiki.

This information is under consideration for the Illinois state wiki. It should not be considered official guidance.

Content

Non-Drivable Roads

| | | | | Walking Trails | | | | | and | | | | | Pedestrian Boardwalks | | | | | are not added to the map in Illinois. Outside some special exceptions, these road types do not add to the routing function of the application.

Special exceptions may be made with the approval by State Managers. For example, a | | | | | Boardwalk | | | | | may be used to support house numbers in situations where they are not assigned to drivable road types. This use must be approved by a State Manager (refer to Area Managers table).

Dirt Roads

Illinois follows this specific guidance on the use of Dirt Road / 4X4 Trail in the state. This supplements the guidance in road types.

Unpaved roads may or may not be classified on IDOT Functional Classification maps. Unpaved roads classified in one of the arterial, collector classes will be mapped as specified in road types guidance. Local and unclassified roads will be mapped as shown in the following table:

		Highway System & Road Surface
		County Highway	Paved Street	Gravel Street	Narrow 2-way Gravel Street^[a]	Soil Street
	examples	CH-14	Main St	Side St	Farm Dr	Farm Ln
Functional Classification	Major Collector	PS	PS	PS	Dirt	Dirt
	Minor Collector	PS	PS	PS	Dirt	Dirt
	Local	PS	Street	Street	Dirt	Dirt
	Unclassified	PS	Street	Dirt	Dirt	Dirt

^a A narrow two-way gravel road is defined as one less than 17 feet from edge to edge. This is less than the width of two FHWA minimum lanes. In all likelihood vehicles approaching from opposite directions would need to leave the roadway to pass.

It is important to remember that the Waze routing server will only consider lower-priority roads (Primary Street, Street, Dirt) near the origin/destination (10km or 6.2mi).
