Supervisors approve bicycling improvements for Little River Turnpike

An illustration from the cover of the Little River Turnpike Corridor Study published in February. 
The Fairfax County Board of Supervisors on July 25 endorsed a list of recommended projects to improve bicycle and pedestrian access that were recommended by the Little River Turnpike Corridor Study.

The cost of all the projects, $6.2 million, would be funded from the county’s Transportation Priorities Plan for fiscal years 2015-20, which was approved by the BoS in 2014.

The short and long-term projects are aimed at improving connectivity and safety for bicyclists along a seven-mile stretch of Route 236 through Annandale between the City of Fairfax and the City of Alexandria. The study also includes improvements for pedestrians, such as shared-use paths, median refuge areas, and crosswalks.

Officials from the Fairfax County Department of Transportation discussed the proposed improvements at a public meeting in May 2016.
