I-95 and Route 123 Interchange

Please note: The project team wants your feedback on draft improvements, watch a video below to learn more and take a survey in English or Spanish through April 19. Read more in the news release.

This STARS (Strategically Targeted Affordable Roadway Solutions) study is assessing potential safety and operational improvements for the interchange and as follow up on the I-95 Corridor Improvement Plan aimed at improving travel along I-95 in Virginia.

There are significant backups and congestion during morning and evening peak periods.

The study is assessing reconfiguring ramps, extending lanes, modifying and relocating traffic signals, access management, and pedestrian, bicycle and transit enhancements to improve traffic flow and safety.

At the interchange, I-95 averages up to 232,000 vehicles a day and Route 123 (Gordon Boulevard) averages up to 71,000.

Route 123 and Old Bridge Road Intersection

This STARS (Strategically Targeted Affordable Roadway Solutions) study is assessing potential safety and operational improvements at the intersection that are causing significant backups and congestion during morning and evening peak periods.

The study is assessing constructing a partial or full grade-separated interchange, modifying and relocating traffic signals, extending lanes, access management, and pedestrian, bicycle and transit enhancements to improve traffic flow and safety.

At the intersection, Route 123 averages 71,000 vehicles a day and Old Bridge Road averages 45,000.

Schedule
Begin Study - March 2020
Virtual Public Involvement - Late Spring 2021
Study Completion - Late Summer 2021

Route 1 and Route 123 Intersection

This STARS (Strategically Targeted Affordable Roadway Solutions) study is assessing potential safety and operational improvements at the intersection. While the recent Route 1 widening project has improved conditions along Route 1, the intersection at Route 123 is expected to experience higher traffic volumes in the future. 

The study is assessing connecting Route 123 and Belmont Bay Drive to reduce traffic at the Route 1 and Occoquan Road intersection, constructing a partial or full grade-separated interchange, and pedestrian, bicycle and transit enhancements to improve traffic flow and safety.

At the intersection, Route 123 averages 19,000 vehicles a day and Route 1 averages 39,000.

Schedule
Begin Study - March 2020
Virtual Public Involvement - Late Spring 2021
Study Completion - Late Summer 2021

Resources

These studies do not set construction dates for any improvements, but develop proposed improvements that localities can pursue for funding and consider including in their comprehensive plans.
