An anonymous group of cyclists called the "Reasonably Polite Seattleites" felt they needed more protection from cars and trucks zipping by, so they took matters into their own hands.
The group installed their own white lines and cones. When the city found out, they thought it was a good idea.
"We thought that it was a good idea, so we decided to implement it. But we made a few tweaks to it," says Pauh Wang, bike advocate with Seattle Department of Transportation
Wang says the citizen-made lanes made sense, so they ran with it, adding better cones along Cherry, a green turn lane, 2 other bike lanes along 7th Avenue, and another on Marion Street.
The City warns- doing it yourself is illegal and dangerous.
"Well we certainly don't encourage citizens to take things into their own hands," Wang says.
Last month a vigilante in Tacoma painted several rogue crosswalks around town.
City officials there removed them, especially after one of them was painted crooked and led directly into traffic.
The City had already budgeted and planned to design bike lanes in the area; citizen improvements just seemed to make them better.
