RailCo LLC installs cable median barrier, concrete barrier, and impact attenuator systems on ITD highway projects across Idaho, with particular depth of experience on the I-84 corridor through the Treasure Valley and the I-15 spine through Eastern Idaho. Our Boise base provides rapid deployment on emergency barrier repairs and competitive mobilization pricing on ITD programmed improvement projects statewide.

ITD Cable Median Barrier Program

ITD has invested significantly in high-tension cable median barrier along I-84 and I-15 to reduce cross-median fatalities on Idaho's divided rural freeways. Idaho's cable barrier specifications reference NCHRP Report 350 and MASH crashworthiness standards and include end anchor designs calibrated for the volcanic soil conditions common on the Snake River Plain. RailCo crews are trained on cable tensioning procedures, post-reset protocols after vehicle impacts, and ITD's emergency repair requirements for restoring damaged cable sections within specified timeframes. We stock cable, posts, and anchor hardware at our Boise yard for rapid response.

Concrete Median and Temporary Barrier

Where median widths are insufficient for cable barrier deflection zones, or where ITD specifies concrete median barrier at bridge approaches and interchange taper points, RailCo installs both precast and cast-in-place concrete barrier per ITD Standard Specifications. We coordinate precast delivery from approved Idaho suppliers and can arrange material logistics for remote project locations across Cassia, Gooding, and Bingham Counties. Temporary concrete barrier (TCB) for construction zone lane shifts and stage construction setups is available for ITD projects throughout the state.

Impact Attenuator Systems

ITD requires MASH TL-3 impact attenuators at interchange gore points, construction zone taper ends, and fixed roadside obstacles throughout the state highway system. RailCo installs approved systems including the REACT 350, QuadGuard, and similar MASH-compliant products. We maintain attenuator inventory at our Boise yard for rapid deployment on emergency replacements and short-duration maintenance projects in Districts 3, 4, 5, and 6.

Frequently Asked Questions

ITD specifies high-tension cable barrier systems from its Qualified Products List, including Brifen Wire Rope Safety Fence and other MASH-approved cable systems. All cable barrier must meet ITD standard plan specifications for post spacing, cable height, anchor design, and tensioning. Idaho's volcanic basalt conditions often require drilling-based post installation rather than driven posts — we bring appropriate equipment to every cable barrier project.

Yes. Cable barrier is designed to deflect in an impact and must be re-tensioned and reset to restore function. RailCo performs emergency cable barrier repair on I-84 and I-15, restoring damaged spans to ITD specification. Our Boise yard maintains cable stock and tensioning equipment for same-day deployment on Treasure Valley sections and next-day response on Eastern Idaho corridors.

Yes. Temporary concrete barrier is required on ITD construction projects for worker protection and traffic separation in stage construction setups. We coordinate precast TCB supply and placement throughout Idaho and can mobilize delivery within 24–48 hours for most ITD District 3 project locations.

Yes. We install and replace impact attenuators on ITD maintenance and construction contracts across Idaho. Our Boise inventory includes MASH TL-3 approved systems for rapid deployment on damaged attenuators at Treasure Valley interchange gore points, and we can ship attenuator units to remote ITD districts with standard freight lead times.
