Q. Can the StarNews help those of us who live in the region better understand what “impact criteria” for commuters and local businesses the state DOT uses when scheduling work that closes our bridges?

A. The N.C. Department of Transportation has a guide that takes into account how long a detour will take a commuter, as well as how long the project itself will last.

“If the project is for six months or less and the additional time traveled is less than 10 minutes, an offsite detour is acceptable,” said Hollie Allen, a DOT spokeswoman.

If, however, the detour is less than five minutes long, the project can stay in place for as long as two years.

The DOT also takes tourist season into account when doing bridge work, trying to conduct work that could cause lane closures after tourist season and wrap it up to do other work before the season officially starts up again.

Why do they allow the bridges to be raised during rush hour?

How does DOT plan to handle traffic when the bridges over the Brunswick River are replaced?
