Long Span Structure Connection
The Long Span Structure Connection (LSSC) is a MASH TL-3 system intended for installation along roadsides where transition from roadside approach guardrail to concrete barrier or bridge barrier is required, either permanent or temporary. The LSSC provides an unsupported span of 9 ft. (2.7 m) from approach guardrail post to concrete barrier, for the purpose of: drainage, drop basic placement, utilities or adequate soil strength for posts. To transition from an approach roadway W-beam guardrail system to the bridge or roadside concrete barrier, the W-beam system first transitions to a Thrie beam approach guardrail, then transitions to the LSSC and is terminated at a bridge or roadside concrete barrier.
