书面表达,你所在的城市交通拥挤现象日趋严重

dear mayor,
I am a student of XX middle school. The crowded traffic condition in front of our school has brought a lot of troubles to the students and their parents. There is a park located at the opposite of our school main gate. The time students enter or leave the school is also the peak hour of the traffic. Many parents send and pick up their children near the school with their own bicycles or vehicle, which makes the traffic even more conjested.
I suggest to build a cross bridge over the street to separate the crowd at the peak hours. Some more parking lots can also offer a relief to the conjestion
