Beijing is facing severe (严重的)  traffic problems."Roads are wider now, but traffic jams (堵塞) often happen every day. " Yuan, a Beijing taxi drivers said.
Beijing government is trying to do something to make traffic jams less.  Before 2007, there were a few subway lines in Beijing. There was only line 1, line 2, line 13 and Batong Line. But now there is line 5, line 10, line 4, the airport fast -track and the Olympic branch line. And there will be 13 subway lines under construction in Beijing at the same time at the end of this year.
The opening of the new subway line is convenient to tourists. Before, arriving in Beijing, many visitors would usually take a taxi to interesting places of Beijing. Today, as soon as people get off the plane, they can take the Airport Express Line, going to different interesting places through the subway lines. The government also strives to open a new line each year from now until 2015. The subway of Beijing reached 300 kilometers in 2010 and it will reach 561 kilometers in 2015.
