Response
Response 1. With respect to the placement of the curb, that system was designed with the curb located with the toe of the curb flush with the backside of the thrie beam. This would be consistent with the schematic you sent.

2. The second issue we discussed was the use of a vertical end section and the need for a tapered corner on the vertical end. We received FHWA approval for the vertical end section with a tapered corner from FHWA and would recommend that the tapered corner be included in the parapet designs if possible. See attached.

Let me know if that addressed your questions.
