California Interstate 280 highway marker



Interstate 280 is a major highway in the Bay Area of Northern California. It runs nearly the length of the San Francisco peninsula, from downtown San Francisco (where it becomes King Street) to San Jose. It serves as a central artery of the peninsula, serving several major cities, including Cupertino, Los Altos, San Bruno, and Daly City. Despite its location in one of California’s biggest urban areas, the views along much of Interstate 280 are quite scenic. In fact, the state has officially recognized it as a scenic byway due to the memorable landscape it passes through.

Our Interstate 280 route marker is an exact replica of the signs that stand along this California highway. It follows the 1961 standards for Interstate signage. This was the first version of the Interstate shield to use a wider blank for three-digit routes. (Before then, the same shield was used for all routes, and the numbers were made narrower until they fit. This did not produce the most legible signage.) Signs of this style were used up until the early 1970s. Our signs are virtually indistinguishable from the original 1960s issue—even the most seasoned collectors will agree!

Our Interstate 280 sign is flat printed on heavy 14-gauge steel.  It is a non-reflective sign, perfect for display as a home decor item. Its glossy finish protects it from the elements when installed outdoors as well. To make installation easier, we’ve included mounting holes, as well. Choose from one of the following sizes:

  • 12.6 in. × 10.8 in. (for decorators on a budget)
  • 21 in. × 18 in. (the size of some early markers)
  • 28 in. × 24 in. (the size most commonly posted in the field)
  • 42 in. × 36 in. (posted when extra emphasis or visibility is needed)

We can make Interstate signs like this with any state and number combination! We can also make US and state route markers, directional and mileage signs, state welcome signs…the sky is the limit. Want something you don’t see on our site? Just contact Jake to place a custom order!
