VDOT is continuing a series of major improvements that began several years ago in the Gainesville area:

  • The 1.3-mile, four-lane University Boulevard, connecting Route 29 and Wellington Road, opened in 2006 at a cost of $18 million. 
  • Widening 3.3 miles of I-66 to eight lanes from Route 234 Business/Sudley Road to the Route 234 Bypass, completed in 2006 for $46 million.
  • Widening 2.5 miles of I-66 to eight lanes from the Route 234 Bypass to Route 29 in Gainesville at a cost of $103 million.
  • The new Route 29 and Linton Hall Road interchange, at a cost of about $216 million.

The commonwealth’s investment in all four projects totals $435 million.

What's Being Done

The new Route 29/Linton Hall Road interchange is one of the largest Linton Hall Video Still of Renderingconstruction projects in Virginia.

The centerpiece is a pair of overpasses: one carrying Route 29 over the Norfolk Southern Railroad, and one carrying Linton Hall and Gallerher roads over the railroad and Route 29. To further improve traffic flow, crews will also widen Route 29 to six lanes and eliminate driveway entrances and two traffic signals between I-66 and Virginia Oaks Drive.

The new, grade-separated interchange at Route 29/Linton Hall Road will create a limited-access facility on Route 29 between Virginia Oaks Drive and Heathcote Boulevard.

Traffic Impacts

Access between Route 29 and Route 55 was closed permanently in Sept. 2010. Drivers can use Heathcote Boulevard to Catharpin Road to Route 55 or Gallerher Road to Route 55.

A traffic switch occurred in August 2013 which placed Route 29 traffic over the railroad tracks. The next traffic switch is scheduled for late 2014 and will grade separate the intersection of Route 29 and Linton Hall Road/Route 55.

Detour Roads
Two temporary roads carry both Route 29 and Linton Hall Road around the the work area for crews to construct the interchange.

Traffic Data
In 2008, I-66 carried 82,000 vehicles a day between Route 29 and the Route 234 Bypass, and is expected to carry more than 175,000 vehicles a day by 2028. Route 29 carried roughly 57,000 vehicles a day through Gainesville and is expected to increase to 87,000 by 2035. Linton Hall Road carried 15,500 vehicles per day in 2005, and by 2035 is expected to grow to 42,000.
