Construction on I-66 outside the Beltway will begin next week.
The project will cost $2 billion and take 4.5 years, or five construction seasons, to complete, according to VDOT Megaprojects director Susan Shaw.
New 22 and a half miles of Express Lanes from the Beltway to Gainesville, new overpasses, thousands of park ride spots and parallel bike paths will be built as part of the project
