Key Challenges & Project Details

  • US 29 & Rio Road Grade Separated Intersection: Construction of a grade separated intersection that will carry US Route 29 through-traffic beneath Rio Road.
  • US Route 29 is an Urban Other Principal Arterial and is part of the National Highway System located within a significant corridor.
  • This is one of the major intersections that will accommodate traffic to and from Berkmar Drive, Hillsdale Drive, and the John Warner Parkway and includes utility relocations.
  • US 29 Widening: Widening/improving US Route 29 for 1.8 miles to complete a six-lane roadway section.
  • Upgrading US 29’s configuration to meet current geometric standards, including stopping sight distance.
  • Berkmar Drive Extension: Extending a 2.5 mile urban connector road to US Route 29, including a 716-ft. long bridge spanning the South Fork of the Rivanna River.
  • The complex bridge design required a single span over the river due to environmental and permitting challenges and incorporates drilled shafts to minimize environmental impacts to the flood plain and nearby wetlands.
  • Replacing an intersection with a single-lane roundabout for free flow of traffic onto the new north/south route, while providing a context-sensitive and traffic-calming element.
  • There will be two 12-ft. travel lanes, a 5-ft. sidewalk on the west side, a 10-ft. shared-use path on the east side, and landscaping along the corridor.
  • Provides right-of-way for a four-lane divided roadway with a 16-ft. raised median.
  • The new Berkmar route passes through a greenfield area in a context-sensitive curvilinear alignment connecting to the roundabout at Town Center Drive avoiding impacts to several cultural resource sites and minimizing impacts to wetlands and stream crossings.
