One thing that I wish I could bring to the attention of DelDOT is this trailblazer assembly from the contractor's documents listed under the project website:
If the facility is to accept non-ETC account holders, the use of "ONLY" is contradictory, and doesn't match the direction as outlined in the MUTCD, page 244, paragraph 11. According the the examples in
Figure 2F-4 for guidance on trailblazers and
Figure 2F-5 for guidance on larger guide signs, the option to accept non-ETC account holders means the the facility should be signed like a standard toll road because it is not exclusively for ETC account holders. I don't have a problem with listing E-ZPass and "Pay By Mail", which are done in other states (see examples below), but at least the use of "ONLY" in this situation seems to be inappropriate.
The example set by
Florida's Turnpike Enterprise for signing entrances to AET facilities where not every user is required to have an ETC account is among the best I've seen. Another example that I like, is North Carolina's
Wake [Toll]way entrance sign assemblies. Maryland's
ICC Entrance signage is okay, in that it's understandable, but it's not an apples-to-apples comparison since it's a "uni-sign".
