Signs and sign support - SD

Barrier Mounted Sign Support (SD-1)

This plan depicts the installation of a sign support on the top of a precast concrete barrier in a median of a divided highway.

In order to be in compliance with the 2003 MUTCD, this sign support design can only be used when the distance from the edge of the sign to the edge of the traffic lane is 12 feet or greater.

Laminated Wood Sign Post (SD-2)

This plan shows a laminated wood sign post and was developed some time ago.

It is no longer used and is a retired Standard Plan. The post was constructed as a hollow plywood box. The idea behind this configuration was that a wooden box would not be as susceptible to warping and splitting as a solid timber post.

There is no specific bid item for the use of this sign post and the user will need to provide this in a project.

Barrier Mounted Sign Post (SD-4)

This plan depicts the fabrication and installation details for a tall sign post mounted on a single slope concrete barrier.

The bottom of the sign panel is mounted fourteen feet above the roadway surface. This height is compliant with the MUTCD and the sign installation can be in narrow medians where the shoulder is four feet wide. The weight of the concrete barrier is critical as it must resist the wind load forces produced by a long level arm (tall sign post). A twenty foot long segment of dual-faced, single sloped barrier has sufficient weight to resist the force.

A pre-cast, New Jersey shaped (type 2) concrete barrier does not have the necessary weight and the drawings should not be modified for this type of installation. The anchor pins for Type 2 concrete Barrier shown in the Standard Plans were developed to resist lateral forces applied near the base of the barrier. These pins would not be effective in resisting the uplifting force produced by high wind loads.
