BRIDGE RAIL
MDS® TL5

A 88 lbs per foot modular steel barrier system 
for temporary or permanent bridge
& work-zone installations

MDS BARRIERS

Minimum Deflection Systems

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-5 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

INSTALLING MDS® TL4 BARRIERS
MDS® BARRIERS installation is a straightforward 4 step process

  1. Install anchor rod into 5″ into bridge deck
  2. Place and attach barriers
  3. Tighten bolts
  4. Mount upper tube rail

SAFE & SECURE
With the ever increasing bridge rehabilitation projects emerging, the need for a light weight, high performance, easy to install 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,

BENEFITS

  • Modular assembly for progressive installation
  • Pre-designed for sound and vision “See through” walls
  • Variety of transitions, terminations and crash cushions available.

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
