The Chesapeake Expressway (Route 168) is a 16.5-mile road between the I-64/I-464 interchange and the North Carolina border. The facility includes three separate roadways: the Oak Grove Connector, a two-mile roadway beginning at the interchange of I-64/464; the Great Bridge Bypass, a four-mile roadway which includes the Hanbury Road Interchange; and the 10.2-mile southern section, which is tolled.

The toll road project was originally planned as a public-private concession under the Virginia Public-Private Transportation Act of 1995, but the state decided that the project could be completed more quickly if it were procured publicly backed by public debt. The details below refer to the tolled section.
