Client: Virginia Department of Transportation (VDOT)

Spanning a 1.5-mile stretch, the project aimed to enhance traffic flow and safety in a notoriously busy area of southbound Interstate 95 that averages about 80,000 vehicles daily. It introduced a new auxiliary lane, facilitating smoother merging between the ramps for Gordon Boulevard (Route 123) and the Prince William Parkway (Route 294), thereby improving safety.

One of the most notable aspects of this project was the hyper-accelerated 16-month design timeline developed by ATCS, significantly shortening the typical project development duration. This acceleration, coupled with practical design solutions such as narrowing shoulder width and strategically using retaining walls to eliminate culvert extensions and minimize right-of-way impacts, not only preserved the surrounding environment but also resulted in a budget reduction. These strategies reflected ATCS’ dedication to technical excellence and fiscal responsibility.

Enhancing Community Serenity through Noise Control

ATCS conducted a accelerated preliminary and final design noise analyses using FHWA’s Traffic Noise Model (TNM) to predict both current and future noise levels. When the project’s widening required physical adjustments to an existing noise wall, our specialists collaborated with VDOT and project team engineers to relocate specific barrier and evaluate overall effectiveness to preserve and improve acoustical benefits and protection for the local community. This effort demonstrates the project’s success in maintaining environmental integrity while adapting to infrastructure enhancements.

Building Stronger Connections with Community Insight

During the December 2019 design public hearing, ATCS introduced interactive experiences, including a 3D fly-through and driving simulator. These innovative approaches enabled participants, including adjacent property owners and residents, to gain insight into the proposed design, clearly visualizing its minimal impact on their homes and overall community well-being.

Community Impact

The new auxiliary lane opened in 2023, providing travelers with safer and easier trips on this heavily-utilized section of the I-95 corridor. Combining technological advancements with a focus on community well-being resulted in a tangible and positive impact on users and the surrounding community.
