The Federal Highway Administration of the U.S. Department of Transportation recently issued two memorandums that may be of interest to TexITE members that work on highway design projects. The first is a memorandum on the Relationship Between Design Speed and Posted Speed. The second is a Proposed Revision of Thirteen Controlling Criteria for Design and New Guidance on Documentation for Design Exceptions. The second memorandum is in reference to the Federal Register Notice from October 7, 2015.
