The interchange at Route 28 and Westfields Boulevard is scheduled to open after tomorrow's morning rush hour, state transportation officials said.
The traffic signal at Westfields will be removed and the bridge, along with six of the eight interchange loops and ramps, will open to traffic, Virginia Department of Transportation officials said in a news release.
Crews will work nonstop through the Columbus Day weekend to complete construction of the remaining two loops, which cannot be finished until traffic is shifted to the new bridge. All of the interchange segments are to be ready in time for Monday morning's rush hour.
The Route 28/Westfields interchange is the fourth of six interchanges to be rebuilt on congested Route 28 in Fairfax and Loudoun counties since a public-private partnership began in October 2002. The former intersection is now a full cloverleaf interchange with a six-lane bridge carrying Westfields Boulevard over Route 28.
With more than 85,000 vehicles a day on Route 28 and 30,000 vehicles a day traveling Westfields Boulevard, traffic has often been reduced to a crawl at the signalized intersection during the morning and evening rush hours, VDOT officials said. Once the interchange opens Friday, vehicles traveling on both Route 28 and the boulevard will no longer wait at a red light for what can be three minutes or more.
The original 14-mile widening of Route 28, from Route 7 in Loudoun County to Interstate 66 in Fairfax County, began in 1987 and was completed in 1991. Funding for the Route 28 corridor is provided in a combination of public and private funds, with 75 percent of the corridor improvements supported by the Route 28 special tax district. State and county funds cover the remainder of the cost.
