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-5 protection.
MDS® TL5 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 time sensitive rehabilitation projects that require relocating MDS® TL5 Barriers during phase oriented construction saving considerable amounts of time, materials & money.
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.
MDS® BARRIERS installation process is a straight forward
4 step process
1. Anchor plate into road surface / bridge deck *5"
2. Place and attach barriers
3. Tighten bolts
4. Mount upper tube rail
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 5 including European Standard EN1317 Test Level H4b.
MDS® BARRIERS transition into all guardrails, concrete barriers and end treatments for seamless integration.
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.
Variable Length Barriers provide positive linear protection over bridge expansion joints expanding more than 27 inches maintaining TL5 protection.

Metal sound barriers are made of galvanized steel, stainless steel or aluminum by cold forming process. Sound barrier panels provide a perfect noise protection and are resistant to atmospheric corrosion in industrial and seaside environments.
Transparent sound barriers are made up of laminated glass panels fitted in aluminum frames.
Each frame is connected to the barrier posts by bolts and safety cables only in the case of extreme bolt failure.
Glass panels maintain excellent transparency in all weather conditions and guarantee maximum noise protection in any location where noise pollution is an issue, such as highways and residential areas.
Protect bridge decks from public abuse and projectiles. Enclose construction sights discouraging visibility and access. Provide full scale wide area protection for high threat areas for absolute containment.

MDS® Variable Length Barriers (VLB) eliminate the gaps on bridge deck expansion joints by expanding and contracting more than 27 inches. Use for continuous protection over bridge expansion joints or were excessive barrier expansion & contraction is anticipated. MDS® VLB barriers can also be used on new bridge expansion joints avoiding the need to build custom design manufacturing.
Genuine US Reflector safety barrier reflective devices define and illuminate roadways around the world. No other reflector comes close to the quality and clarity of high power prismatic technology. Use on all MDS® BARRIER products and standard concrete barriers and poles for absolute crystal clear safety in all colors.
Not all reflective devices are made equal. Discover BarrierGlow, a photoluminescent stripe of light creating linial visibility. BarrierGlow is a complimentary addition to traditional reflective devices. Improve motorist visibility through workzones.
