Why Route 123 Matters

Route 123 serves as a critical connector between Fairfax County, Prince William County, I-95, Mason Neck, and the Occoquan area. Transportation conditions along this corridor affect commuters, residents, emergency services, businesses, and recreational travel.

Because the corridor connects multiple communities and transportation systems, many issues cannot be understood through a single project alone.

Connection to TAC

The Route 123 Corridor demonstrates why transportation information should be organized by corridor as well as by individual project. Many transportation issues cross community boundaries and involve multiple agencies, projects, and funding sources.
