The barriers in the article photograph are DOT certified. They are routinely used to channel traffic flow on sections of highway under construction, to contain building materials like crushed stone for road base, sand, etc. When the project is completed they either go into storage for the next stretch of highway or they are sold as surplus.
- mike_d 4y agoThe barriers in the three photos that show them are called bin blocks, and not DOT approved. Traffic approved barriers are required to have a deflection mechanism (that is why the common jersey barriers and K-rails you see have angled faces) or shock absorption mechanism. You can't have a flat face that doesn't move. There are also composition requirements. Bin blocks are just made from remnant materials.
- doodlebugging 4y agoThank you for this information. I did not know that, obviously. I have seen bin blocks and barriers for sale in auctions of highway-related materials and bin blocks alongside highways and assumed that they must be DOT approved.
