A simple design solution.  Great urban sculpture. Witty and inventive.  Possibly low cost. 

The median strip is the reserved area separating opposing lanes of traffic.  In many municipalities they function as green belts, a landscape design with trees, beautiful plantings, lawn grasses, etc. In locations such as New York City's Park Avenue there is a mixture of garden art, landscape sculpture, seasonal plantings. But this site specific landscape installation works with the grit of the city.  The humor of the twin yellow lines somewhat symbolic of the bumpy ride on city streets, the stoping and starting of city traffic.
