About this file
This is a Question and Answer document for the Illinois Department of Transportation's bid #25-494DOT-FINAD-B-45875 regarding the purchase of Trailer Mounted Message Boards and Arrow Boards. The document addresses two similar questions from vendors concerning the specified message board panel dimensions of 35"x78", which vendors noted are significantly smaller than typical DOT message boards (75"x132" or 134"x76") used on interstate highways. The vendors also pointed out that the specified 8" minimum character size does not meet MUTCD (Manual on Uniform Traffic Control Devices) requirements of 18" characters.
In response to both questions, the document indicates that Specification #507-60-10 has been revised and attached, though the revised specifications are not included in this document. The response suggests that the original specifications contained incorrect dimensions that did not meet standard requirements for highway message boards.

Question and Answers
Question 1: I had a question about the sign cabinet size. In the 507-60-10 attachment, it has the following listed:
“The message panel shall be formed of reinforced aluminum and shall be approximately 35"x78". Each line shall be of an angled design to provide the optimum visibility and reduce glare.”
That panel size is a mid sized board and not usually used in on Interstate travel, as the letters do not meet the MUTCD. The letter size is also listed at a minimum of 8” characters, the MUTCD calls out 18” characters. Can you confirm that IDOT is looking for a smaller board than what they have had in the past? For reference, the full size board is 75” x 132”.
Answer 2: Spec # 507-60-10 has been revised and attached.
Question 2: We have reviewed bid number 25-494DOT-FINAD-B-45875 and it looks like the message board panel dimensions are very small compared to the DOT message boards we typically manufacture for Illinois.
The dimensions listed on this solicitation reflect 35” x 78” compared to 134" x 76" based on previous Illinois DOT specifications. Is this an error? Please confirm.
Message Sign Panel:
The message panel shall be formed of reinforced aluminum and shall be approximately 35"x78". Each line shall be of an angled design to provide the optimum visibility and reduce glare.
Answer 2: Spec # 507-60-10 has been revised and attached.
