The improvements include widening about a quarter-mile of Spring Street from just west of Herndon Parkway to Fairfax County Parkway to allow for additional through and turn lanes. Additional turn lanes on Herndon Parkway are also being constructed at the Spring Street intersection.
The project also includes a new sidewalk and eight-foot-wide cycle track along northbound Herndon Parkway that will eventually connect the new Herndon Metro station to the Washington & Old Dominion Trail. A cycle track combines the user experience of a separated path with the on-street infrastructure of a conventional bike lane.
Other pedestrian improvements include a new sidewalk along eastbound Spring Street from Sunset Park Drive to Fairfax County Parkway, enhancing existing sidewalks on both sides of Spring Street and replacing the sidewalk along southbound Herndon Parkway.
Within the project limits, Spring Street averages about 32,000 vehicles a day and Herndon Parkway averages about 15,000.The project is scheduled for completion in late 2024. For more information, view the project webpage https://www.virginiadot.org/projects/northernvirginia/e_spring_st.asp
