Dan Henry, inventor of directional pavement markings for organized rides passed away

Dan Henry marking system, approved by The League of American Bicyclists. This system
makes following the route easier, makes marking more consistent, and also makes route marking guidelines clearer and easier for the workers to understand.

All circles will be 10" in diameter. Directional lines should not extend inside the circle. In most instances, the turn symbols will be painted on the pavement close to the right shoulder of the road. The route markings inside state parks may be placed on signs located on the right shoulder of the road, when it is not permissible to paint the symbols on the pavement. The route markings will be a visible color, such as yellow or orange, and will be as follows:
The workers responsible for marking the route will be instructed to use the following guidelines when placing the markings on the pavement:
Place the first route marker 100 feet prior to the turn. The second route marker will be placed 20 feet prior to the turn. The third route marker will be placed on the pavement 10 feet after the turn. (Illustration 1.) Some turns, like those on downgrades or difficult intersections, will have four markers on them. The spacing will be 150 feet prior to the turn, 100 feet prior to the turn, 20 feet prior to the turn, and 10 feet after the turn.
Dan Henry, 1913-2012
Dan Henry, a longtime bicycle advocacy leader, passed away last week, just a few days shy of his 99th birthday. Henry was the inventor of directional pavement markings commonly used to guide participants along the route of organized bicycling events, and the 1992 recipient of the League's 1992 Paul Dudley White Medal.

 Dan Henry, one of the grand old men of American cycling passed away on March 7 in Solvang, just a few days shy of his 99th birthday and the Solvang Century. 
Many of the locals remember him and his wife Trudi riding their tandem nearly every day around the Santa Ynez Valley until she passed away five years ago. And of course there is the Dan Henry Bike Route on Alamo Pintado and Grand Avenue in Los Olivos. 
But few know the wide range of his exploits As a young pilot he was a skywriter, towed advertising banners, and was an aerial photographer when he was in his twenties. He then spent 25 years as commercial pilot for American Airlines, starting in 1939 flying first DC-2, DC-3’s and finally the Boeing 707 the, first passenger jet.. 
His biking interests were wide-ranging. He participated in and led cycling tours through the eastern US and Europe with the International Bicycle Touring Society. Those route markings you see for the Solvang Century and other rides are called Dan Henry Markers. 
Dan was an innovator. He designed and built a road bike with a front and rear suspension, and a “sling” saddle that he used for years. 
He also was an early advocate for biking facilities in Santa Barbara County and promoted and wrote poetry celebrating the benefits of cycling. 
In 1992 the League of American Bicyclists awarded Dan their prestigious Paul Dudley White award for his efforts on behalf of cyclists over the years. 
Dan was one of a kind and will be missed.

  1. Thanks for sharing this news, which just appeared in our local club discussion forum.

    Here is a link to a webpage I've set up with more good Dan things.

    He wrote a poem about painting road arrows. It's on there.
