For those who don't know what I am talking about, logo signs are the big blue signs containing the logos of food, gas, lodging, camping, attraction, and 24-hour pharmacies businesses prior to an interchange and at the off-ramps of an interchange.
Historically, logo signs were only permitted in rural areas, however, in 2000 provisions for allowing these signs in urban areas were added to the 2000 edition of the Manual on Uniform Traffic Control Devices. Nevertheless, some states continue to restrict their logo sign programs only to rural areas. As far as I know, the following states have adopted the provisions for allowing logo signs in urban areas:
- Arizona (currently being installed in the Phoenix area, coming soon to the Tucson area)
- Colorado (currently being installed in the Denver area, coming soon to the Colorado Springs area)
- Florida
- Georgia
- Iowa
- Louisiana
- Massachusetts
- Minnesota
- Nevada
- North Carolina
- Texas
- Virginia
- Washington (not in Seattle itself, but in all of the suburbs)
- Wisconsin
I live in Arizona and the signs started to go up in late 2013 and continues to be expanded on more freeways. Phoenix should be complete by the end of 2016 except on Loop 303 which is planned for 2018.
