Venice is today one of the most vibrant and eclectic areas of Southern California and it continues a tradition of progressive social change involving prominent Westsiders. The Venice Family Clinic is the largest free clinic in the country. Venice is an unusually pedestrian-oriented area for Los Angeles: many of its houses actually have their principal entries from pedestrian-only streets, and have house numbers on these footpaths. (Automobile access is by alleys in the rear.) However, like much of Los Angeles, Venice is also well-known for traffic congestion. It lies 2 miles away from the nearest freeway, and its unusually dense network of narrow streets was not planned for the demands of modern traffic. Mindful of the tourist nature of much of the district's vehicle traffic, though, its residents have successfully fought numerous attempts to extend the Marina Freeway (CA-90) into southern Venice.
