This document from the Fairfax County Department of Transportation evaluates the impacts of building or not building the proposed Bi-County Parkway on Fairfax County roads. It provides background on the project, noting its evolution from the Tri-County Parkway and its intended purpose to improve north-south connections. Traffic forecasts from 2013 predict the parkway would attract some traffic from parallel roads like Gum Springs Road but have only minor benefits for roads in Fairfax County. It concludes that while some parallel roads may see reduced traffic, the overall volume on the parkway represents additional trips rather than diversions.

Merrifield Nursery Emergency Gravity Sewer ReplacementFairfax County
During a routine Closed-Circuit Television (CCTV) Camera inspection by Wastewater Collection Division (WCD), it was found that 45 linear feet of 8-inch asbestos reinforced concrete pipe (RCP) between MH-292 to MH-291 was within imminent danger of failing. The bottom of the RCP was missing within the 45 linear feet of repair and the pipe was on the verge of surcharging. After an immediate pre-construction meeting with Merrifield Nursery, it was agreed to work from 6pm-10am everyday of the week to avoid disruption and potentially placing patrons at risk during the biggest time of the year for Merrifield Garden Center. The contractor mobilized to the site and began the 20-foot excavation to replace 45 linear feet of broken gravity sewer. The project started on March 14th, 2022 and was substantially complete on March 23, 2022.
The Sully Basins Stormwater Pond Retrofits project was substantially completed on April 19, 2022. The project is located within the Cub Run watershed. The project consisted of repair and enhancement of multiple stormwater basins, 0326DP, 0964DP and 1484DP. The project also included construction of new stone cascades, stone weir basin structures and the construction of wetlands with high and low marsh areas. The project will facilitate improved sediment removal and improve downstream water quality using forebays and micro pools. Aquatic and natural habitat were also added within the three basins.

In a May 9, 2024 paper, Juri Opitz from the University of Zurich, along with Shira Wein and Nathan Schneider form Georgetown University, discussed the importance of linguistic expertise in natural language processing (NLP) in an era dominated by large language models (LLMs).
The authors explained that while machine translation (MT) previously relied heavily on linguists, the landscape has shifted. “Linguistics is no longer front and center in the way we build NLP systems,” they said. With the emergence of LLMs, which can generate fluent text without the need for specialized modules to handle grammar or semantic coherence, the need for linguistic expertise in NLP is being questioned.

Conclusions
• Bi-County Parkway does attract traffic away from other
parallel roads, primarily Gum Springs Road and Route 15
• Bi-County Parkway has a minor benefit for parallel roads
in Fairfax County (Route 28, Pleasant Valley Road and
the Capital Beltway)
• Total projected traffic volume on the Bi-County Parkway is
greater than the reductions on other parallel roadways;
constructing the Bi-County Parkway appears to result in
additional trips
