Although Arizona follows the general road naming and road type guidelines of the USA, there are some road naming rules specific to our state that all Arizona editors MUST follow.
They are included in this section.
Elevation Editing or "Seagulling"
Seagulling is the editing practice of changing the elevation of one segment as it crosses immediately over/under another segment. This is not necessary and does not serve any navigation purpose. Elevations are used to delineate the crossing segments so they do not create a routing problem. Instead of cutting a segment into small pieces to accommodate the elevation change, it is better to leave the entire segment at the desired elevation.
In Arizona, all primary freeway segments are set to Ground elevation, unless they cross another freeway segment, then one will either be +1 or -1 elevation.
State Highway Naming
Arizona uses SR-## for all state routes and highways.
- Do not add additional road names to the Alternate Names field.
Valley Freeway Nicknames
In every city, transportation landmarks are given nicknames. It can be very confusing to anyone not familiar with the area. This is a list of nicknames for all the valley freeways.
Stack – A four-level interchange connecting I-10 and I-17; located west of downtown Phoenix near 19th Avenue and McDowell Road.
Mini-Stack – A four-level interchange linking I-10 to State Route 51 and Loop 202 Red Mountain Freeway; located south of McDowell Road and east of 16th Street.
North Stack– Another four-level interchange, this one is located at the I-17 and Loop 101, north of Bell Road.
Split– The interchange where I-10 splits or merges – depending on your direction of travel – with I-17 near Phoenix Sky Harbor International Airport. Westbound I-10 splits into lanes that allow drivers to head north on I-17 or continue west on I-10.
SuperRedTan– A multi-tiered interchange in east Mesa where US 60 Superstition Freeway, Loop 202 Red Mountain and Loop 202 Santan meet. SuperRedTan is formed by taking part of each freeway’s name – Superstition, Red Mountain and Santan.
Broadway Curve– Southeast of the Split, this rush-hour-challenged section I-10 is near Broadway Road, and SR 143, by the Phoenix-Tempe border.
Durango Curve– The curved section of I-17 near Durango Street is located southwest of downtown Phoenix.
The city name field is not to be filled in. Only road segments that pass along the boundary of a city/town will receive a city name and locked to a higher level to prevent tampering. The sole purpose for this practice is to easily identify city boundaries. The city area itself is already identified by Waze. Adding a city name to a road could potentially cause routing issues, especially if one road changes from one city to another.
Alternate names are not to be used on any Arizona roadways. They do not show up in on the map and have been known to have adverse routing effects. For other reasons, please see the explanation on City Names.
Functional Classification implementation
FUNCTIONAL CLASSIFICATION IMPLEMENTATION INTO WAZE FOR THE STATE OF ARIZONA HAS BEEN COMPLETED.
PLEASE REFER TO THIS FORUM TOPIC ON THE MATTER Road Types (USA) – comprehensive overhaul of drivable roads
Waze USA has agreed to set a national standard in accordance with the FHWA manual for establishing road classification types in Waze. The following information is in relation to how this is to be understood/applied for the state of Arizona.
Arizona to Waze Functional Classification conversion
ADOT GIS class and color description
The Arizona Classification and Color scheme come from the official Arizona D.O.T (ADOT) Functional Classification (FC) map that is published by ADOT. The legend shows what classifications ADOT uses and what color is assigned to each class.
Please refer to the GIS FC map link in the Helpful Links section below for access to the map.
This screenshot shows how the FC and color scheme appear in the GIS map.
