Midwest Roadside Safety Facility
What's New:
Temporary Barrier Transition
This project consisted of the development of a transition design for the highest priorty situation
in order to provide work zone designers with an important tool for connecting temporary concrete
barriers to permanent barriers.
The system was successfully tested with the 2270P vehicle at the TL-3 impact conditions.
Temporary Barrier Termination
This project consisted of developing a simple ground anchor system that resists longitudinal motion
in order to simulate the effects of additional barrier segments extending upstream from the end of the
length of need of the free-standing temporary barrier system.
The system was successfully tested with the 2270P vehicle at the TL-3 impact conditions.
Test Level 1 Timber Curb-Type Railing for Use on Transverse, Timber, Nail- Laminated Deck Bridges
This project consisted of adapting and modifying a crashworthy TL-1 timber bridge railing system for
use on nail-laminated, transverse timber deck bridges, while using the proposed MASH 08 guidelines.
The system was successfully tested with the 2270P vehicle at the TL-1 impact conditions.
High-Tension Cable Median Barrier
This project consists of the development of a non-proprietary 4-strand, high-tension cable median
barrier which can be used in a v-ditch as steep as 4:1. The system has been successfully tested with
the 2270P vehicle at the TL-3 impact conditions.
MGS Transition Utilizing Standard Posts and Hardware
This project consists of developing a simplified version of the recently developed Midwest Guardrail
System (MGS) W-beam to thrie-beam stiff bridge rail transition which uses various sizes and lengths of
steel posts and wood blockouts. The simplified version reduces the number of different posts and
blockouts contained in the system. The system has been successfully tested with the 2270P vehicle at the
TL-3 impact conditions.
