Develop Enhanced Protection of Median Openings between Parallel Bridge Structures

When divided highways span a hazard, engineers often design two separate bridges with the bridge rail ends protected by guardrail installations, leaving an opening between the parallel bridge structures possibly resulting in a gap in roadside protection. The combination of the sloped median ditch and the approach guardrail can direct errant motorists between the two bridge structures and into the underlying hazard. The risk increases when the spanned hazard is another roadway with motorists traveling below the parallel bridges. Unfortunately, these median openings have fatal crashes in Texas and across the country. The original project, 0-7021, developed the Median Opening Protection System (MOPS) and began the crash testing. The research team will address this safety issue as follows: 1) Identify characteristics of high-risk locations that can benefit from implementation of a MOPS, and 2) Evaluate the MOPS with full-scale crash testing.
