MASH TL-3 Transition Between Median Guardrail and Median Concrete Barrier

Report Number(s): 0-6990-R1

Description: The installation consisted of a double-sided, 31-inch-tall W-beam median guardrail attached to a concrete terminal barrier via W-beam terminal connectors. A second 17-inch-high W-beam section rub rail was installed just below the guardrail on both sides for a distance of approximately 14 ft upstream of the concrete terminal barrier. The total length of the installation was 95 ft 117 /16 inches. The W-beam medial guardrail was installed on both sides of 72-inch-long wide flange guardrail posts and terminated on the downstream end with a simple terminal that provides anchorage functionality to the system. The rails were offset from the posts by W-beam blockouts.
