historically overlooked, culverts are an integral part of the highway system
and like other infrastructure they are subject to deterioration. ODOT is
responsible for maintaining these drainage systems to assure safety of the
public and protect highway assets.
ODOT has embarked on a comprehensive program to inventory and accurately assess
the condition of culverts located along the State’s highways. The focus is
on culverts that range from 12 inches up to 20 feet in span. The goal of this
effort is to set a consistent statewide standard for inventorying and rating
culverts, as well as uploading this information into ODOT’s Drainage Facilities
Management System database.
|Drainage ID Markers |
|The purpose of the Drainage ID Markers is to set a consistent statewide standard for marking culverts less than 20 feet in culvert span. The installation of drainage markers is optional and must be marked using standards from the following options:
- Type 1: The Type 1 marker is a green thermoplastic tape installed along the inlet edge of the pavement for quick identification of the culvert.
- The Type 2 marker is a white background non-reflective aluminum paddle with black lettering that is mounted to a steel post or attached to a permanent feature. The paddle is marked with the facility’s drainage ID (DFI), mile point, and a green strip near the top.
