ODOT Standard - Figure 1

Allowable retrofit to preexisting walls/parapets.  A
contractor would like to use a short 3’-3/4” piece of rail with a splice at
post 1 at this location instead of the 14’ panel.

Figure 2

We looked at this briefly. Because you are using nested thrie beam in that area and we have the narrow post spacing, there is less concern for high rail loads in the area of the proposed splice and short thrie section.

Thus, we believe it would be acceptable to use the shorter thrie beam piece as long as the nesting is retained.
