Seasonal postings are used when. The road's structural analysis indicates permanent postings, such as during the freeze/thaw damage cycle, may not be necessary.
Penn DOT Publication 23, Chapter 1, defines the Freeze/Thaw Period as "the calendar period between approximately February 15th and April 15th, during which times the temperature results in changes (weakening) to the structural strength of the road surface. The POSTING AUTHORITY may require additional restrictions due to severe weather and other unforeseen circumstances." A website search produced no specific guidelines or requirements for axle weight reduction.
Hauling authorized by Letters of Local Determination (LoLDs) shall be prohibited during the Freeze/Thaw Period unless a modification is specifically
requested by the User and approved by the Posting Authority. The User must confirm the effective dates of the Freeze/Thaw Period with the District.
