Keep Traffic Flowing Safely Around Your Work Zone
When a construction project requires a street closure, the safety of drivers, cyclists, and your contractors is paramount. Installing official, MUTCD-compliant Road Closed signs is a legal and ethical obligation that ensures motorist preparation and smooth traffic regulation.
At Signs River, we fabricate heavy-duty, long-lasting road closed signs and reflective traffic signages designed to meet the strict administrative codes of NYC DOT, NYSDOT, and federal safety boards. Crafted from rust-resistant aluminum, our traffic boards remain highly visible day and night.

Glass Safety & Thermal Compatibility
Applying standard vinyl graphics to insulated double-pane glass or tinted commercial windows can introduce thermal stress. If a film absorbs too much solar radiation, it can cause the glass unit to experience rapid heat absorption and expansion, risking cracking or seal failure.
At Signs River, we perform meticulous thermal stress analysis during our site survey. We determine the exact glass configuration (clear, annealed, tinted, Low-E, tempered) and exposure index (south-facing, shaded) to match the correct polymeric or perforated film. We fully back all our glass installations with a zero-crack safety guarantee.
Glass Compatibility Chart
✔ Single Pane (Clear / Tempered): 100% Compatible (All Films)
✔ Double Pane (IGU Clear): 100% Compatible (Low-Absorption & White-Backed Perforated Films)
✔ Low-E Coated Windows: 100% Compatible (Exterior-applied Specialty Films Only)
✔ Reflective / Tinted Glass: 100% Compatible (Heat-Conforming Polymeric Cast Films Only)

View DetailsFrequently Asked Questions
What aluminum thickness do you use for NYC DOT signs?
We use standard 0.080-inch (2mm) heavy-gauge rust-free aluminum panels. This thickness is structural and meets all municipal, state, and federal wind load rules.What is the difference between Engineer Grade and HIP reflectivity?
Engineer Grade Reflective sheeting is standard for low-speed parking lots and secondary streets. High-Intensity Prismatic (HIP) features micro-prisms that redirect light with much higher efficiency, making it the legal standard for busy public highways and nighttime road closures.Can I customize a Road Closed sign with specific dates?
Yes, we print custom road closed signs with pre-printed dates or integrated dry-erase/re-writable date boxes so you can keep neighbors and drivers informed.
