Overhead bridges can be seen in many parts of Singapore, in the place where traffic is very heavy and crossing the road is 　1　 .

These bridges can make people 　2　 　roads safely. Overhead bridges are used in very much the same way as zebra crossings.

They are more efficient (效率高的), 　3　 　less convenient (方便的) because people have to climb up a lot of steps. This is inconvenient to the old. When people 　4　 　an overhead bridge, they do not hold up (阻挡) traffic. But when they cross a 　5　 　road using a zebra crossing, traffic is held up. This is 　6　 　the government (政府) has 　7　 　many overhead bridges to help people and 　8　 　traffic moving at the same time.

The government of Singapore has 　9　 　a lot of money building these bridges. For their own safety, people should be given hope to use them 　10　 　rushing across the road. Old people may find it a little 　11　 　climbing up and down the steps, but it is still much safer than walking across the road 　12　 　all the moving traffic.

Overhead bridges are very useful. People, 　13　 　old and young, should 　14　 　use them. This will stop accidents 　15　 　happening.
