Each year, the Northern Virginia Transportation Alliance invites leaders in regional transportation to report on important developments in their area of expertise. They get five minutes each, so they distill their comments down to the most important changes and challenges. Here's what they highlighted at last week's session.

I-66 corridor

The Virginia Department of Transportation has been targeting problem areas inside and outside the Capital Beltway.

l In June, VDOT began the first of several planned spot improvements to add capacity on I-66 west inside the Beltway. The first is between George Mason Drive/Fairfax Drive and Sycamore Street. It is scheduled to be done in December 2011.

lThis summer, VDOT finished widening I-66 in both directions out to Route 29 in Gainesville.

l Construction will begin early in 2011 on an interchange at Route 29 and Linton Hall Road in Gainesville. The project, scheduled for completion in summer 2014, will remove a long-standing bottleneck.

l VDOT plans to repave 6.5 miles of I-66 from the Beltway west to Route 50, with scheduled completion by fall 2012.

l VDOT is launching a study of topics that include greater transit service along the corridor, tolling, traffic management options including high-occupancy vehicle and high-occupancy tolllanes and localized improvements on I-66 from the Beltway west to Route 15. A draft environmental impact statement on options should be ready by June 2012.

Base realignment

Tom Fahrney, VDOT's coordinator for problems stemming from the huge personnel shifts required by the federal Base Realignment and Closure program, focused on attempts to ease congestion likely to occur around Fort Belvoir and the Mark Center.

l Two highway projects near Fort Belvoir are well along. VDOT this month opened a two-mile extension of the Fairfax County Parkway. I-95 is being widened for six miles between Route 123 and the Fairfax County Parkway. A fourth northbound lane opened in December 2009. A fourth southbound lane is scheduled to open this fall.

l Work continues on ramps and interchanges that will open up access between the parkway, I-95, and the federal bases as thousands of additional employees arrive.

l That effort around Newington "really pales in comparison to the issues we will have at the Mark Center," Fahrney said.

l Several proposed ways of easing traffic at the Mark Center, including an HOV flyover ramp connecting to I-395, have been rejected for lack of community support or engineering issues.
