WASHINGTON, June 6 - It is no secret that campaign contributions sometimes lead to lucrative official favors. Rarely, though, are the tradeoffs quite as obvious as in the twisted case of Coconut Road.

The road, a stretch of pavement near Fort Myers, Fla., that touches five golf clubs on its way to the Gulf of Mexico, is the target of a $10 million earmark that appeared mysteriously in a 2006 transportation bill written by Representative Don Young, Republican of Alaska.

Mr. Young, who last year steered more than $200 million to a so-called bridge to nowhere reaching 80 people on Gravina Island, Alaska, has no constituents in Florida.
