Highway congestion in and around Washington, D.C., and the region’s aging infrastructure have become issues of concern for business and government leaders in the area. Many are calling for expansion of mass transit, which could ease gridlock, help the environment, and spur economic development.

In addition to governmental assistance, the private sector also has a role to play, said David L. Winstead, a real estate attorney at Ballard Spahr and the former transportation secretary in Maryland. Mr. Winstead pointed out that, although shoring up the Transportation Trust Fund must be addressed in the 2012 legislative session, “there is an excellent example in the White Flint Partnership to provide innovative transportation improvements such as rapid transit, which will bring jobs, growth, taxes, and amenities” to Rockville.
