The new Route 29/Linton Hall Road interchange began construction in June 2011 and is scheduled to be completed in the summer of 2015. At an overall cost of $230 million, the project's main features include: four new bridges, Route 29/Linton Hall grade-separation and traffic signal removal; a five-foot concrete sidewalk and ten-foot shared use path; ten retaining walls and architectural treatments; roadway lighting and landscaping; temporary detour roads to keep traffic moving during construction.

This project represents a continuation of a series of major improvements that began several years ago in the Gainesville area. Three projects previously completed include 1.3-mile, four-lane University Boulevard connecting Route 29 and Wellington Road; I-66 widening to eight lanes from Route 234/Sudley Road to the Route 234 Bypass, and then to Gainesville. The Commonwealth's total investment in all four projects totals about $400 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 are also widening Route 29 to six lanes and eliminating 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

Traffic will be shifted around early/mid-May 2015 onto the new southbound Route 29 bridge over the railroad tracks and the new Linton Hall Road/Route 55 overpass. With this traffic switch, the eastbound I-66 ramp to SB Rt. 29 will be re-opened and the traffic signal at Linton Hall and Rt. 29 will be removed. At that time, work will begin on the ramp from Rt. 55 to SB Rt. 29 and the ramp from northbound Rt. 29 to Linton Hall. Detours will be in place while these ramps are under construction.

The final traffic switch is scheduled to occur in June 2015 with the completion of all ramps connecting Linton Hall/Rt. 55 to Rt. 29.

Detour Roads
Two temporary roads carry both Route 29 and Linton Hall Road around 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.
