BIRMINGHAM, AL (WBRC) - People who drive along U.S. Highway 280 can't help but notice numerous surveying crews that are sharing the road with them.
Road crews from the Alabama Department of Transportation are working in three spots: Red Mountain to Interstate 459, I-459 to Valleydale Road and Valleydale Road to the city of Chelsea.
The survey work being done is in preparation for an elevated toll road.
"Everything we've done up till now has been done off aerial mapping, aerial photography," said ALDOT division engineer Brian Davis. "But it's not as accurate as a ground run survey."
Crews are looking at the lanes, determining the elevation, the soil type and the depth of rock. They're also working with the utility companies to locate lines underground. Davis says it's all an effort to make sure concept and reality match.
"Geometrically it will work," Davis says. "Lane balance it will work. Meeting the demand…it will work. But you continue to refine your define to make sure it's good in all aspects."
