The Los Angeles Times can tell you how close you live to a freeway. Just enter your address and the LA Times will show you your house and the nearest freeway on an interactive map. It will also tell you if you are within the 500 foot zone where air pollution is highest or if you are within the 1,000 foot zone (where scientists advise that you shouldn't live).
The map is part of the newspaper's report into why L.A. keeps building homes within 500 feet of freeways. If you zoom in on a freeway on the interactive map you can see the most polluted 500 and 1,000 feet zones - shown in red and yellow respectively on the map. If you zoom out a little the zones will disappear and instead dots will show you how many people live within 1,000 feet of the freeway.
Later on in the LA Times report another interactive map shows you how many building permits the city has issued within 1,000 feet of a freeway since 2005. This map includes a slider control which allow you to change the year to see how these permits have accumulated over the years.
