Thanks for the opportunity to review the proposed hazard mitigation design. From my review of the attached discussion and details, I assume that the authors are planning to allow impacting vehicles to travel up and over the sloped berm and onto the top of a single-slope concrete median barrier. This action would result in vehicles rolling off of the top of the barrier or traveling forward and entering the separated median barrier and bridge pier region. Second, angled impacts near the nose of the berm but slightly down the side could result in the vehicle being tripped and launched over the barrier system, potentially rolling over as well. As such, I do not recommend that the Ohio DOT nor any municipality use the sloped berm concept described below to treat the tall, single-slope concrete median barrier. Please feel free to discuss this matter with me at your convenience!
