The purpose of this project is to replace the existing at-grade intersection of Routes 29 and 666 with a diamond interchange to improve safety and capacity.
In 1970, when the portion of Route 29 known as the Culpeper Bypass was widened to four lanes, a diamond interchange was envisioned for future construction at this intersection. This project became a priority in 2008 with the opening of Eastern View High School and the associated increase in vehicle, pedestrian and bicycle traffic.
A 2009 interchange study and an interchange justification request, prepared in 2011, explored four different interchange designs: diamond, partial cloverleaf, single-point urban and roundabout. The diamond interchange was recommended due to its lowest initial cost, shortest construction period, flexibility for future modifications and familiarity to motorists.
Route 666 carries approximately 5,600 vehicles per day through the current intersection.
What is Proposed?
Construction of the new interchange will include raising Route 666 to an overhead crossing of Route 29 and widening the roadway to four lanes divided by a 28-foot raised median. Bike lanes will be added on both sides of the road, as well as a five-foot-wide sidewalk on the south side and a 10-foot-wide shared use path on the north side.
Traffic will be maintained on the existing roads during the first phase of construction, as the westbound portion of the new Route 666 roadway is built. In the second phase, traffic will switch to the new roadway to allow for demolition of the existing roads and construction of the new eastbound half of Route 666 and its ramps.
The latest estimated project costs from the 2012-17 Six-Year Improvement Program:
Total Cost: $35,335,038
Design and Engineering: $4,276,509
Right of Way Acquisition and Utility Relocation: $6,347,904
This project will be financed using federal funds.
