A dry forecast does not settle a fog-related travel question

Present

NWS identifies reduced visibility as the central travel concern. Check the actual destination and travel period rather than treating a rain icon as a complete road report.

Visibility is a separate question

The National Weather Service’s fog overview explains that dense fog can create hazards for drivers, mariners and aviators. It also notes that reduced visibility can affect aircraft takeoff and landing and lead to delays.

A simple expectation of dry weather therefore does not answer every visibility-related travel question.

Check the actual journey

For a trip between Gretna and Danville or toward South Boston, check current official conditions for the intended location and travel period. If visibility could affect the plan, resolve the transport arrangement with the operator or responsible organizer rather than assuming that a familiar route will behave as it did on a previous day.

This is an evergreen planning guide, not a current fog warning, aviation instruction or assurance that any road is open. Gretna Junction has not inspected a route or obtained a present local visibility measurement.

Use the current official forecast and alerts before departure; this article supplies no alternate route, expected delay or time when conditions will clear.
