Virginia has entered into a public-private partnership to build 29 miles of new lanes along I-95 that will be open to carpools and individuals willing to pay a toll.

The partnership (similar to the one that transferred control over the state’s IT infrastructure to Northrop-Grumman) will have Irving, Tex.-based Fluor Enterprises build the lanes, which will then be operated by Australian company Transurban. (The two companies are operating together as 95 Express Lanes, LLC.)

The new lanes will parallel the highway from Garrisonville Road in Stafford County to Edsall Road in Fairfax County. It will include new park-and-ride lots, and more spaces in some existing lots.

Groundbreaking is expect to begin sometime in August.

There are a lot of details. Read them over at the Washington Post.
