Interstate 99

In 2006, the Virginia General Assembly directed the Secretary of Transportation to initiate a study to determine the interest of affected states in the construction of a new Interstate highway (I-99). I-99 would allow long-distance travelers to bypass the I-95 bottleneck in the Baltimore–Washington metropolitan area. This would be separate from the existing Interstate 99 in New York and Pennsylvania.

I-99 would travel from I-95 in Wilson, North Carolina, to another point on I-95 in Christiana, Delaware (12 miles (19 km) from Wilmington, Delaware). It would renumber the limited access Delaware Route 1 (DE 1) and would parallel U.S. Route 13 (US 13) through the Delmarva Peninsula and using the existing Chesapeake Bay Bridge–Tunnel. It would travel through Norfolk, Virginia, traveling concurrently with existing interstates where possible. I-99 would continue to travel parallel to US 13 until it enters North Carolina, where it would travel parallel to US 258 until ending on I-95 in Wilson.

Another option is for I-99 to parallel US 17 in North Carolina, and have it end in Charleston, South Carolina. One option that was never fully planned was to connect the proposed Christiana, Delaware, I-99 east coast section and existing Bedford, Pennsylvania, I-99 section by having I-99 travel concurrently with existing interstates including I-476 and I-76.
