When there is so much traffic on the roads, it is sometimes quicker to walk than to go by car

During rush hours, walking gives me much more pleasure than driving in the heavy traffic.

It is faster to walk than to drive in the heavy traffic at certain time of the day.

The traffic is always so heavy that you’d better walk to work; it’s quicker.

There is so much traffic these days that it is more pleasant to walk than to drive.
