 The City of Tacoma recently came up with a creative solution to a challenging situation: How to design a redirectional barrier for a railroad overcrossing that would also satisfy the site's "rails to sails" artistic theme. Take a peek at their tugboat-themed barrier planter box to the right. |

The state of Florida commissioned the University of Florida to design, develop, and evaluate a new type of portable concrete longitudinal barrier. The primary function of the barrier is to prevent vehicular penetration into the roadside environment. This curb/barrier design successfully passed crash testing conforming to NCHRP Report 350 Test Level 2 (70km/h). |

This is an example of a Low Profile Bridge Rail as detailed on the plan sheet from the Midwest Roadside Safety Facility. This plan sheet illustrates the details for end view, rebar details, rebar longitudinal details, and the isometric rail view. Included are some photos to better illustrate these details. For more information see FHWA approval letter with link below: http://safety.fhwa.dot.gov/fourthlevel/hardware/barriers/pdf/b116.pdf For you convenience this downloadable dgn file is available to those with Microstation V8. Select the plan sheet to the right then download the file.

The low profile barrier was constructed at a location along State Route 303, north of Bremerton, for posted speeds of 45-50 mph. |
Sloped end treatments were used in the 45 mph section. |
Median barrier configurations such as these may be landscaped or capped with concrete. |
