CHICAGO (CBS) — The Illinois Toll Highway Authority is considering a proposal by CBS Outdoor to put digital billboards on the tollway oasis buildings.

The signs would be big–40 feet by 12 feet–and would be installed on either side of the buildings. They would be clearly visible to approaching drivers and would change about every ten seconds.

The toll authority, according to the Daily Herald, is concerned they might distract drivers. If the billboards go up, the agency will monitor whether they cause accidents.

CBS Outdoor, a subsidiary of the company that owns Newsradio 780 and CBS 2 (WBBM-TV), says it operates digital billboards in San Francisco and New York and there is no evidence they’ve caused any crashes.
