|Description Text||Attached is a sketch for a 72” pier protection strut going down to meet a 54” glare-screen median barrier. We are wondering what slope should be used to transition from the 72” strut down to the 54” median barrier? We also are wondering if there needs to be anything special done to go from a 36” wide vertical pier protection strut transitioning to the 54” tall “F” style median barrier.|

|Response||In general, we have recommended the use of 8H:1V height transitions for permanent concrete barriers in order to reduce the propensity for vehicle gouging and snag on the upper concrete surface. We also noted this vertical slope in a prior Pooled Fund consulting inquiry found below.
In terms of the location where the 54” tall barrier transitions down to 36” barrier, I might suggest the use of the same 100 ft longitudinal distance recommended in the weblink above and for 54” tall barrier in advance of the multi-pier configuration.
Please let me know if you have any further questions. Thanks!
