Construction is expected to begin around Aug. 1 on the most expensive highway contract ever awarded by the Alabama Department of Transportation.
The nearly $169 million project will provide for 1½ miles of ramps and bridges that will connect Corridor X with Interstate 65 at Birmingham. It will feature an interchange 85 feet tall.
The department's division engineer, Brian Davis, told The Birmingham News that it's the most complicated highway project ever in the Birmingham area.
Atlanta-based Archer Western Contractors is supposed to complete the project in 2014. It will essentially finish the Alabama portion of Corridor X between Birmingham and Memphis, Tennessee.
