A guardrail terminal incorporates an impact head of open front configuration adapted with a rear portion as a funnel disposed with the narrow end of the funnel facing forward which will flatten the W beam guardrail as it moves down the beam when impacted by a vehicle. Tension is maintained on the beam by flat strips connected from the beam through the open front of the impact head to a front anchor post. A reverse direction bracket with slotted bolt holes such that the slots open toward the traffic direction connected at the back of the impact head for connection with the guardrail allow for reverse direction impacts to be accommodated. |
