Proceed following the pedestrian route and in Corner Position Number order (see corner position and curb ramp position diagram).

Curb Ramp Position is a number given to each curb ramp beginning with Corner Position 1. The first curb ramp encountered in the increasing curb ramp position diagram).

For example an island between corner positions 1 and 2 and is closer to corner 2 has a corner position number of 2A (See corner position and counter-clockwise around the intersection, numbering consecutive 1 through the end of corners. An "A" is added to the number for an island.

Corner Position is based on traveling in the increasing mile point direction, beginning with the first corner on the right and proceeding

Milepoint of an intersection is based on the mile point of the center of the intersection listed to the hundredth of a mile.

Overlay lapping mileage is listed as "z" mileage.

4) Mileage Type is used when there are multiple locations of the same mile point on a section of highway.

Check the Digital Video Log to be sure of the direction.

When there is a separated highway there will be an "I" roadway and a "D" roadway.

For most highways, the "I" direction is south and east. Note I-5 does not follow this rule. Generally "I" will be used.

and "D" for decreasing mile point direction.

3) Roadway ID is a one letter code used to identify alignment. There are two possible letter codes; "I" for increasing mile point direction

If the intersection is not located on a connection use 00 for the code.

and click on Map Position to see Information.

Use the Identify Features tool on the ODOT Trans GIS Road Network layer > Hwy Network-Colored layer for visual reference. Select "Identify Features"

2) Highway Suffix is a letter format assigned to frontage roads and connections to identify the unique connection, for example AA or AB.

Valid numbers are 001-493.

1) The Highway Number is a 3 digit number (not the route number) assigned to all state highways by ODOT.

There is a four part format for the code: Highway Number; Highway Suffix; Roadway ID, Mileage Type.
