About the California Sponsor A Highway® Program:

California Average Daily Traffic counts (ADTs) reach up to 365,500 cars every day on some of California's busiest roadways. With the average vehicle carrying 1.8 passengers, businesses that purchase a sponsorship in these areas are likely to receive upwards of 660,000 impressions every single day. That's the lowest cost per thousand (CPM) of any other outdoor media!

The Sign:

For each segment sponsored, one litter removal sign with the sponsor recognition panel is placed on the shoulder of the highway , facing traffic within each two-mile segment. Signs are teal with white reflective letters and measure 42" x 54" in size.

The sponsor recognition panel measures 21" x 45." AHMC's art department will work with you to design your sponsor panel for the best visibility and exposure.

California Ramps:

Ramp signs are placed along the on-ramp and off-ramp of major highways. They are slightly smaller than a regular sign, with the sponsor panel measuring 30" x 15".

Signs are available on a first-come, first-served basis.
