An aerial bridge on the Washington & Old Dominion Trail over Wiehle Avenue could be constructed by October 2022.
Earlier this week, the Fairfax County Board of Supervisors approved final design plans for the project, which is expected to cost $11.4 million, according to the Fairfax County Department of Transportation.
The bridge includes retaining walls and directional access to Wiehle Avenue for trail users. Wiehle Avenue would be widened from Sunset Hills Road to the Reston Fire Station property in order to make way for future on-road bike lanes.
Plans have long been identified by the Reston Metrorail Access Group’s plan to improve vehicle, bicycle and pedestrian access near the new Wiehle-Reston East Metrorail Station.
Robin Geiger, a spokeswoman for FCOD, said design plans are currently 90 percent complete. The project timeline expects utility design and relocation to take a little over a year-and-a-half, land acquisition to take a year, construction authorization and permitting to take eight months and construction to take one year.
Hunter Mill District Supervisor Cathy Hudgins said the project faces the challenge of ensuring the bridge maintains synergy in the midst of urban properties that are coming together down the street.
The developer of the Isaac Newtown properties, which are being redeveloped, said they were concerned the project’s scale interferes with the development. County officials said they would work with the developer to mitigate any concerns.
However, according to FCDOT, the height of the bridge is necessary because the design of the bridge uses existing infrastructure in order to cut cost costs. The height is also vital to meet grade requirements and requirements stipulated by the Americans with Disabilities Act.
