All roadways from interstate highways to unimproved trail roads are named with a field called Route ID. The Route IDs for each roadway follow specific criteria.

Route IDs are divided into four categories:

Type I consists of state highways with I, US, or N prefixes.

Type II includes state spurs, state connecting links, and state recreation roads.

Type III includes all municipal streets and county roads.

Type IV includes all roadway ramps.

Roads on the state highway and interstate system have a 3-digit or 4-digit Route ID that matches the highway or interstate number.

Acceptable suffixes for Type I are:

For example, I-80 has a Route ID of 080. The Route ID of I-680 is 680.

Links, spurs, and state recreation roads have a 4-digit or 5-digit Route ID.

Highway links and spurs Route IDs have 4 digits.

State recreation road Route IDs have 4 or 5 digits. When typing in the five digits for state recreation roads, such as 10122, 10118, 10137, etc., users must enter a zero beforehand to ensure the ID displays.

A spur is a state highway that branches from a state highway to a municipality or state park not already on a highway. The principal characteristic is that only one end of the highway connects with another state highway. A connecting link is a state highway that extends between and connects with two other state highways. Normally, a connecting link is short in length. A recreation road is a county road that connects a state recreation area to a state highway, and/or has been developed and improved with monies from the State Recreation Road Fund in accordance with Section 39-1390, Nebraska Statutes.

The Route ID starts with:

The 2nd and 3rd characters are the county number. The 4th character is a letter that differentiates that specific link, spur, or recreation road in that county.

Recreation roads may have a 5th character to differentiate the section of recreation road further. For example, L01E is a linking highway in Adams County. The prefix of L denotes a link. The county number for Adams County is 01. The E differentiates this linking highway from other links in Adams County.

Route IDs R89B and R89BC are examples of state recreation roads showing a county number designation followed by a letter designation for each recreational area within a county. For Route ID R89BC, the B denotes the main road leading to a specific area, and the C indicates interior roads within a specific recreational area.

Municipal streets and county roads may have a 4-digit or 6-digit Route ID.

Major municipal streets and county roads typically have a 4-digit Route ID that consists of all numbers. Smaller municipal streets and county roads typically have a 6-digit Route ID. The 6-digit municipal street Route ID starts with a 2-digit city code. Similarly, the 6-digit county road Route ID starts with a 2-digit county number. The remaining four digits are a local road name code that may be based on the street’s name. County roads with a P in any position after the county number, such as 01P129, indicate a partial county road that is located between two section lines. Other examples would be Route ID YUWLTS for Walnut Street in Yutan and the Route ID 01008 for 70th Street in Adams County.

Ramps are roadways that connect two grade separated roadways. Ramps have a 6-digit Route ID. The Route ID starts with a 4-digit Route ID of the dominate highway connected to the ramp. The 5th digit is the ramp type. The 6th digit is letter or number that designates that specific ramp. For example, 0080LD is the Route ID for a loop ramp for I-80.

The ramp types are:

C – Collector‐Distributor

F – Free Right

L – Loop

R – Ramp

W – Weigh Station

Z – Rest Area
