This guardrail was developed by the Connecticut Department of Transportation. It is a weathering high strength steel backed wood rail supported by W6x15 weathering high strength steel posts on 10 foot centers. The rail element consists of 6" x 12" wood beams backed with 6" x 3/8" thick steel plates and splices to provide tensile continuity. Height to the top of the rail is 30". A wood block measuring 4" deep x 8" wide x 11" high separates the rail element from the posts to minimize snagging. This barrier was tested to NCHRP Report 350, TL-3, and is approved by the Federal Highway Administration. It is known as Merritt Parkway Aesthetic Guardrail. Can be used for state parks and other areas that require an aesthetic appearance.
