Maryland- Maryland Gov. Larry Hogan proposed a $9 billion public-private partnership (P3) to add four new traffic lanes to Interstate 495 and four lanes to Interstate 270. Intended to decrease congestion in the U.S. capital region, Hogan wants private developers to design, build, finance, operate and maintain the added lanes. Hogan also wants to build toll lanes on the Baltimore-Washington Parkway, which is operated by the U.S. Department of Interior, and transfer ownership of the roadways to Maryland.
After the ownership is transferred, the Maryland Transportation Authority would be responsible for building and maintaining the roadways. Hogan’s plan was announced just a few months after signing an agreement with the U.S Department of Transportation to build a $2 billion, 16-mile light rail project in the Maryland suburbs near Washington. The Purple Line project is being constructed through a P3, and the federal government is contributing nearly $900 million.
