Position 12 of the NLF_ID code. Differentiates ‘mainline’ routes from ‘child’ routes or is used to differentiate routes that would otherwise have the same number.
RIMS user derives from roadway changes communicated through County Engineers, or other sources.
Based on provided source information, RIMS user assigns appropriate system code value.
This could be a number, letter, or special character—asterisk (*) is the default value and represents no suffix. Examples: For CR1, positions 7-12 for County Route 1 in Stark County are coded as 00001* For CR1A, positions 7-12 for Stark County Route 1A are coded as 00001A

RIMS user derives from roadway changes communicated through Director’s Journal, County Engineers, or other sources.

N/A

Route Type further indicates the primary ownership of the route segment with some exceptions. For some business purposes there are routes assigned an NLF_ID of County or Township when situated within a municipal boundary. Because they reside inside a city boundary, they are municipal routes even when assigned a ROUTE_TYPE of CR or TR. ODOT tracks this information using a combination of fields including MILEAGE_CLASS and MUNI_CODE_LEFT and/or MUNI_CODE_RIGHT. For example, if a route assigned as Route Type CR is located within a municipal boundary it will be coded as MILEAGE_CLASS = 2 and the MUNI_CODE_LEFT and MUNI_CODE_RIGHT will be populated.

​RIMS user derives from roadway changes communicated through the Director's Journal, County Engineers, or other sources.​
​Based on provided source information, RIMS user assigns appropriate system code value.​
​Jurisdiction indicates the primary ownership of the route segment with some exceptions. For some business purposes there are routes assigned an NLF_ID of County (C) or Township (T) when situated within a municipal boundary. Because they reside inside a city boundary, they are municipal routes even when assigned a Jurisdiction of C or T. ODOT tracks this information using a combination of fields including MILEAGE_CLASS and MUNI_CODE_LEFT and/or MUNI_CODE_RIGHT. For example, if a route assigned as Jurisdiction C is located within a municipal boundary it will be coded as MILEAGE_CLASS = 2 and the MUNI_CODE_LEFT and MUNI_CODE_RIGHT will be populated.

This is the primary key field which allows ODOT’s graphic roadway network geometric segments to be linked to business data attributes.
OTS/RIGIS
NLF_ID is the basis for identifying unique roadway segments in ODOT’s geospatial geometric map layers. It is the key field that ties roadway graphics to all ODOT business data attributes that can be displayed on a map.

​System aggregation of multiple fields within RIMS.

​RIMS user determines based on business requirements.

Positions 7-11 Route Number (ROUTE_NBR): The Director of Transportation, County Commissioners, Township Trustees, or Office of Technical Services (OTS) assign transportation route identifications. Each state system route number is unique within Ohio. Local roadways are unique within each county. Route numbers are always five digits and zero-padded. For example, RIMS stores the route number for Interstate 71 as 00071 and the route number for State Route 161 as 00161. 
Position 12 Route Suffix Code (ROUTE_SUFFIX_CD): This field has legacy meaning from ODOT’s Local Roadway System Database and is only used on an off-state system route. It is an extension of the Route Number (ROUTE_NBR). It has no specific meaning. Its purpose is to differentiate routes that would otherwise have the same number. This could be a number, letter, or special character—asterisk (*) is the default value and represents no suffix. 
Examples: 
  • For CR1, positions 7-12 for County Route 1 in Stark County are coded as 00001* 
  • For CR1A, positions 7-12 for Stark County Route 1A are coded as 00001A 
Position 13 Route Extension Code (ROUTE_EXTENSION_CD): Defines a specified characteristic of a state transportation facility. Each character has a specific meaning: 
Code=Description 
*=Default (a regular route with no special qualifier)
A Alternate
B Bypass
C Spur or connector
D Directional alternate (1st within a county)
F Directional alternate (2nd within a county)
G Directional alternate (3rd within a county)
I Interchange roadway
J Waiting for final disposition (abandonment or transfer)
K Turnpike
N Northbound
P Proposed (not built) This code is an exception and can be used on an off- state system route to designate a proposed route
S Southbound
T Temporary route
X Express lanes 
Position 14 Cardinality Code (CARDINALITY_CD): Roadways in Ohio are usually inventoried in the predominant route direction, from south to north and west to east. On a divided highway, there would be two NLF_IDs, one for each direction of the roadway. Both routes are inventoried with logpoints shown in the cardinal direction (e.g., south to north and west to east.)
  • The Cardinality Code (CARDINALITY_CD) is C when the route is south to north and west to east. 
  • The Cardinality Code (CARDINALITY_CD) is N when the route does not follow a cardinal direction.​
