Old Point Comfort near Fort Monroe. Known as the Merrimack Trail, the road was a major additional highway which was built in the years prior to the creation of the Interstate Highway System, and was replaced as a major through route by Interstate 64, in segments as that new road was completed. Small portions of the roadway on the Peninsula originally signed as SR 168 became portions of State Route 30 (from Anderson's Corner to Croaker) and Interstate 64 (Exit 231 to Exit 238). However, most of it from Exit 238 on I-64 east was redesignated as State Route 143, which continues to serve as an alternative to U.S. Route 60 most of its length. After Interstate 64 was completed on the Peninsula, both Routes 60 and 143 with many at-grade intersections and businesses became more major conduits for local traffic than through-traffic routes. Major intersections Chesapeake Expressway The Chesapeake Expressway is the name of the portion of SR 168 that is a toll road in Chesapeake, Virginia built chiefly to facilitate tourist traffic from the Hampton Roads cities en route to the Outer Banks of North Carolina. Built to freeway standards, this expressway travels from U.S. Route 17, Interstate 64, and Interstate 464 in northern Chesapeake to near the North Carolina border in the southern part of the city, and traverses the eastern edge of the Great Dismal Swamp, meeting North Carolina Highway 168 at the state line. The one toll plaza is located near Indian Creek Road. Construction began in 1999 and the road fully opened in 2001. , tolls for a 2-axle passenger vehicle are $8.00 during weekends between Memorial Day and Labor Day, and $4.00 at all other times (tolls were previously $2.00 and then $3.00 at all times). E-ZPass is accepted. State Route 168 Business State Route 168 Business is a business route of SR 168. The entire length is also known as Battlefield Boulevard. This was originally a part of SR 168 before the Chesapeake Expressway was completed. This highway is often used to avoid the toll on the main expressway—drivers travelling North make a left turn at VA 168 Business, then enter the expressway at Hillcrest Parkway. Great Bridge Bridge The Great Bridge Bridge is a double-leaf rolling bascule drawbridge that carries Battlefield Blvd.(SR 168 Business) and spans the Atlantic Intracoastal Waterway in Chesapeake, Virginia.
