Visualize 2050 Background


Even before the Visualize 2045 plan was completed in June 2022, the Transportation Planning Board was already thinking about the development of the next National Capital Regional Plan, Visualize 2050.  On June 16, 2021, the TPB resolved the development of Visualize 2050 will consider multiple build scenarios and how those scenarios impact the region’s adopted goals and targets, including the reduction of greenhouse gas emissions, and that all projects must be resubmitted for consideration with the exception of projects already substantially underway. 

The TPB initiated work on Visualize 2050 immediately following approval of the Visualize 2045 plan, and plan development follows the TPB’s approved schedule with an adoption date of June 2025. Learn more.

Preparing for the Future


The National Capital Region boasts a robust multimodal transportation system that serves people traveling through the region on roads, rails, and by air. Within the region, an intricate integrated network serves motorists, transit riders, walkers, bikers, and other travelers. The region is a very active place that supports many government and private employers, is home to millions of people, and hosts millions of visitors each year.

The next National Capital Region Transportation Plan is currently under development for the metropolitan region including Washington DC and parts of Maryland and Virginia. The plan is called Visualize 2050 and documents the region’s plan to improve people’s travel experiences through the year 2050. You are invited to learn more, get involved, and help make our region better.
