In an ever increasing effort to save money the U.S. Postal Service is encouraging green routes. Neither the elements nor a bad economy can stop U.S. mail carriers. But to save a little green the USPS is doing a little adjusting.

"Right now we are in the process of doing minor route adjustments. They'll help us eliminate using a car which will help cut costs. They call them green routes," said Mason City Postmaster Scott Pardoe.

Pardoe says it will take about a month to shift around his routes. By adding a block or two to each route the post office hopes to eliminate at least on mail truck on the road.

"They probably drive 6-8 miles a day but that's a lot if you remember the mail come 302 days a year."

Pardoe says that none of the carriers should be worried about their jobs. Customers may see some changes but Pardoe says nothing will get lost in delivery.

"They might have a different mail carrier and the times, when we adjust routes, we try to make them as close as possible to what they're receiving now."

Cities all across the country are adopting green routes. Smaller communities will be the last affected. Of course there is also the added benefits for the environment with hundreds of fewer mail trucks on the road.
