Median barriers in Indiana are almost always constructed by slip forming in order to speed up construction and reduce costs. When light poles are mounted to the top of median barriers, Contractors will often lower the base of the light pole such that the tops of the anchor bolts are below the typical top surface of the barrier, see picture in attached PDF. This is done to prevent the slip forming machine from running into the anchor bolts. Without this modification of the INDOT Standards, the slip forming operation has to be terminated at the light poles and those locations are required to be hand formed and poured after the remaining barrier has been slip formed. It appears to us that the current practice, as shown in the attached PDF, has the potential of creating a snagging hazard at the light poles, since a nearly vertical face is formed in the barrier immediately adjacent to the light poles. Just an FYI our light poles are typically spaced somewhere around ever 250 ft. Our questions are:
We would appreciate any thoughts on this matter. Thank you
I have some thoughts on this.
