| FROM: | T. V. Rountree, P. E. |
| State Bridge Design Engineer | |
| DATE: | December 2, 1999 |
| SUBJECT: | Pedestrian Box Culverts |
Due to the common fit-up problems associated with pre-cast box culverts and the pedestrian tripping problems associated therewith, it will be the Structure Design Unit’s policy to disallow the pre-cast option for all four sided box culverts intended for pedestrian traffic. Place the following note on the plans in lieu of the standard note allowing the option:
NO PRECAST REINFORCED BOX CULVERT OPTION WILL BE ALLOWED
The Design Manual will be updated in the future.
