GR-1.1 – Installation height to the top of guardrail now 29” +/-1” for new installations, +/-2.5” for resurfacings
 
The following guardrail drawings have been updated to refer to GR-1.1 for the installation height of the Type 5 guardrail, no other design modifications were made to the drawings.
  • GR-2.1
  • GR-2.2
  • GR-2.3
  • GR-2.4
  • GR-3.1
  • GR-3.2
  • GR-3.3
  • GR-3.4
  • GR-3.5
  • GR-3.6
  • GR-4.1
  • GR-4.2
 
Please note:
-This change was necessary as research showed that the lower 27-inch W-beam guardrail height does not meet NCHRP Report 350 crash testing criteria.
-Parts and minimum embedment depth will remain the same for 29” height installations.
- Design heights for Bridge Terminal Assemblies (BTAs) and proprietary end treatments have not changed.  They are crashworthy as designed. The contractor may connect to these existing designs and transition to the 29” over a length of 25 ft.
-the generic Type A and Type T guardrail anchors should be set to a top height of 29”
- When new installations are connecting to existing installations, the Contractor may transition to the 29” rail height over a length of 25 feet.
- For guardrail repair sections less than 200 feet, replace in kind. Otherwise the guardrail should be installed at the 29” height and can transition back to the existing height over a length of 25’.
April 20, 2012​
  • BP 3.1 - Text in Red modified for clarification
January 20, 2012​
  • BP 3.1 - Text in Red is for Pay Item clarification
  • GR-4.2 The washers were added in the anchor bracket assembly on page 1, and the wording of the W-Beam End section was changed from "Flared" to "Rounded" in the driveway opening detail on Page 2.
  • GR-4.5 was updated to show that it can be used with 4:1 foreslopes
  • GR-6.3 is a new drawing.  It is a crashworthy Thrie Beam Bullnose for pier protection which we expect will be useful in locations where previously outdated non-crashworthy systems (Type A sloped-down guardrail ends, W-Beam Bullnoses) need to be replaced, particularly where existing draininge structures limit the footprint.​
