612.03 Construction
612.03.01 Regulatory and Warning Signs, and Guide Sign, Type GA Steel “U” Post Supports
If sign placement conflicts with existing conditions, obtain RE approval to adjust the sign location. Determine the sign post lengths based on the final grade. Mount sign panels on breakaway steel “U” post sign supports. For signs located behind guide rails or other roadside barriers, mount sign panels on steel “U” post sign supports without the breakaway assembly. After mounting sign panels, notify the RE. The RE will examine the sign panels at night for glare. If directed by the RE, adjust the sign panels to eliminate glare. Shim signs mounted on 2 posts either at all bolts on 1 of the posts, or at the proper upper or lower bolts on both posts. Shim signs mounted on a single post at either the upper or lower bolts, whichever best minimizes glare. Install shims between the back of the sign and the post. Ensure that the sign does not deform, and that the nuts and bolts are securely tightened.

Install anchor, hinge, bracket and coupling assemblies according to the manufacturer’s recommendations. The RE may require the system manufacturer’s representative to be present at all times during the installation to provide on-site technical support.
