MONTGOMERY CO., Va. -

A nightmare is what some commuters are calling the I-81 detour. They will have to take a detour that will start at the Christiansburg exit, then onto 460 and then back on at 132.

“I'm not going to like it. We've got to go 460 and it's a dark road especially at four or five o'clock in the morning,” said commuter Beverly Davis.

Davis is the manager of a gas station off of the Ironto exit. It falls in between the detour, which she says will be bad for business.

“We have a lot of morning traffic and overnight traffic that going to be all detoured to 460, so that will bypass us completely,” said Davis.

On top of falling sales, Davis says she will probably have to wake up earlier to make it to work on time. The extensive pavement improvement project will stretch between mile markers 121 and 125. It’s also expected to last around eight days and that's pending weather conditions.

"I know it's going to be a traffic headache but the roads need to be repaved,” said truck driver Michael Peterson.

Peterson has been driving trucks for 20 years; particularly the 81 stretch for 17 years several times a day. He says he's all for the construction project.

“It's gotten so rough down through there, it beats you all to pieces coming down the road. Its holes out there that's probably three or four inches deep,” said Peterson.
