for temporary or permanent bridge
& work-zone installations
MDS BARRIERS
Minimum Deflection Systems
- High Performance
- Cost Effective
- Easy Installation
TL4 MDS® BARRIERS
MDS® Barriers are a high performance aesthetically engineered bridge rail System designed for both new and existing bridge rehabilitation projects. Modular design facilitates assembly for permanent installations and can be easily installed and relocated for temporary installations. Developed specifically for bridges due to its light weight and high impact TL-4 protection.
- Eliminates concrete barrier bridge dead weight by 90%
- Reduces the risk of bridge collapse during short- and long-term projects
- Provides the highest MDS® TL4 crash impact rating in a portable barrier
PERMANENT AND TEMPORARY
MDS® TL4 BARRIERS can be installed on structures as permanent or temporary barrier when mounted back to back or used as bridge rail especially during construction and tim

SAFE & SECURE
With the ever increasing bridge rehabilitation projects emerging, the need for a light weight, high performance, easy to install TL4 and TL5 barrier for work zone safety has been a challenge. MDS® BARRIERS have been developed to provide the highest level of protection allowing job sites to start and end faster. The design simplicity of SRS anchoring system has no exposed plates or bolts that extend out from the barrier eliminating snagging especially in snow removing environments.
Crash Attenuatrors
MDS® BARRIERS transition have smooth intergration into crash attenuators providing non snag openings,

NOISE & VISUAL PROTECTION
MDS® BARRIERS are pre-designed to integrate noise-protection sound barriers and site walls within a single barrier system providing considerable savings in terms of occupied space, supporting substructures and overall cost. The special backward positioning of the noise-protection barrier requires less lateral space on the bridge deck and also makes the disposal of snow easier when exposed to freezing climates
PROVEN MDS® TL4 PERFORMANCE
MDS® Barriers have been tested to meet the highest performance standards in the world, passing both the American Standard NCHRP-350 Report 350 and MASH Test Level 4 including European Standard EN1317 Test Level H2.
TRANSITIONS
MDS® BARRIERS transition into all guardrails, concrete barriers and end treatments for seamless integration
